282 fired with filter before show from previous show completed.
284 Add 'date' handling for solr-pz2.xsl.
286 --- 1.6.33 2013/08/13
288 pz:authentication may carry user group password. If pz:authentication
289 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
290 authentication. Two forms are allowed
293 If no blanks are present, open authentication is in use (as before).
295 Fix {prev,next}recid elements that are returned by record
296 command. These were incorrect in versions 1.6.23 thru 1.6.32.

313 Local limit for fields of type "generic" (ie text fields) are
314 now normalized by mergekey rule before comparison takes place.
315 Before, no normalization took place and comparsion was, thus, exact.
317 New facility: dynamic rank , which allows ranking to be changed
318 for an existing result set. The rank can be set for search or
319 show. This overrides the rank for metadata elements (which fields
322 New facility:dynamic mergekey , which allows mergekey to be changed
323 for an existing result set. The mergekey can be set for search or
326 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
327 Also, allow ports to be given as names (not just integers).
328 Fix @-notation on systems that don't support IPV6 sockets.

332 Add MasterKey Connect configuration. Refer to section "non-standard
333 databases" for more information.
335 Allow timeformat for log to be specified with option -m (as Metaproxy
338 New Debian package pazpar2-dbg.
340 Fix NULL ptr reference of se->relevance. If a new search is initiated
341 and a CCL query fails to parse, Pazpar2 could crash.
343 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
344 existed in 1.6.29 only.
346 --- 1.6.29 2013/04/05
348 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
349 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
350 changed by setting "host" attribute for the "listen" element.
352 Change semantics of pz:extendrecs. Allow for repeated fetches .
353 pz:extendrecs is now the number of extra records to fetch (was total
356 --- 1.6.28 2013/03/21
358 Fix hang or memory violation if show occurred before a search. (not that
359 it makes much sense to perform a show before a search).
361 --- 1.6.27 2013/03/08
363 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
366 --- 1.6.26 2013/03/08
368 New pz:metadata attribute, empty="empty-value" for Pazpar2's
369 internal representation. With this attribute, Pazpar2 treates an empty
370 pz:metadata type as having the value for "empty" - if empty.
372 New setting, pz:extendrecs, which triggers extended fetch of records
373 for a database beyond pz:maxrecs for a show command.
375 Fix warning that was falsely issued for "missing limitmap".
377 Log message for Pazpart start/stop changed. Now using same style as
378 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
380 --- 1.6.25 2013/02/07
382 Fix hang of 2nd command=show with esn/syntax given.
384 --- 1.6.24 2013/01/18
386 New merge attribute type: 'first', which takes all metadata fields
387 from first target that returns the particular field.
389 --- 1.6.23 2013/01/02
391 Extend info command with hostname and YAZ SHA1
392 Indent results for both command stat and info.
394 Allow limit on merged content. The new configuration metadata
395 element, limitcluster, configures that a metadata element (name) be used
396 as limit name for search. Applies to the whole service (ie all targets),
397 unlike pz:limitmap which is configured per-target (database).
399 New feature: limitmap local:* matches against all metadata fields.
401 Allow repeated list in limitmap spec . Separated by comma. For
402 example: value="local:title,rpn:@attr 1=4".
404 New element <message> in bytarget response. Holds diagnostic message
405 of code (say 'Unsupported Use Attribute' for Bib-1 114).
407 Improved logging for record ingestion failures.
409 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
410 when YAZ is compiled without ICU support.
412 --- 1.6.22 2012/10/11
414 Requires YAZ-4.2.40 to support native solr support.
416 Fix and improve logic handling whether or not to re-do search on sort
417 order changes. A sort order with change in ascending/descending only
418 whould not trigger a new search, which is required for targets with
419 native sorting capabilities. Each client is now checked if instructions
420 (sortmap) exist for native sorting and only client that does requires
421 it is researched. Other clients is just re-ingesting the records,
422 they already have. The resultset is now cleared if any researching
425 Connection sharing between session has broken since version 1.6.8 with
426 introduction of logic that would minimize searching if pazpar2 could
427 detect this based on same query and limits and partly sort order.
428 This could lead to segementations violations.
430 Added a chapter in the manaul about relevance ranking.
432 --- 1.6.21 2012/09/24
434 Rank tweak: follow=number will increase mult by number if two terms
435 occur next to each other; number-1 if they are one term apart , .. 0
436 if they are number a part (all in order). Default is 0 (following
437 terms has no effect).
439 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
440 value given by lead and l is length from beginning of field where
441 term occurs (l=0 for first term, l=1 for second term, ..). Default
444 Rank tweak: length=strategy. length="linear" if mult is to be divided
445 by length (existing, default behavior), length="log" if mult is to be
446 divided by log2(1+length), length="none" if mult is not to be affected
449 --- 1.6.20 2012/09/21
451 Rank algorithm details may be printed as part of show response in
452 element <relevance_info>.. This is only printed if <rank debug="yes"/>
455 Record as returned by show/record command have a minimal indentation
456 which makes things human-readable.
458 New configuration of default sorting criteria (sort-default) in
459 service definition. If no criteria is defined it will be as before
462 Search command now supports sort parameter just as the show command.
463 If no parameter is give, it will use the service sort-default value.
465 --- 1.6.19 2012/09/18
467 Rank algorithm skips strings that gets normalized to empty string.
468 For example, & and ! could map to the empty string. The weight for
469 those terms is now 0 (as if they were not part of the query).
471 Rank algorithm does not use CCL from limitmap; only from the query
472 parameter (user query).
476 --- 1.6.18 2012/09/17
478 Rank algorithm configurable by 'rank' element inside service. So far
479 only, attribute 'cluster' is recognized. If cluster="yes", multiple
480 records inside a cluster boosts higher than single records. This
481 is default behavior and existing behavior. cluster="no" takes the
482 average score of each record in a cluster.
484 --- 1.6.17 2012/09/05
486 Fix bad re-use of connections (connections with changing proxy should not
489 --- 1.6.16 2012/08/22
491 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
492 resultset and sorting when the sort order is position. However this will be done on
493 every client poll, which will make pazpar2 continuing reset and fetching.
494 It should only be done on FIRST request where the sort order change.
496 Fix an issue on suggestion option: Also disable suggestions on empty string.
498 Clean up in turbo marc stylesheet.
500 Remove the hardcoded size of termlists.
502 --- 1.6.15 2012/06/27
504 New facility: ccldirective may be given in service definition. Allows
505 CCL parsing to be customized a bit, such as defining names of operators
508 New facility: raw record by checksum, rather than offset. The record
509 command optionally takes checksum which identifies certain record from
512 New facility: per field ranking. Rank may be given as M [F N] where
513 M is default rank and N is rank for CCL terms from field F.
515 --- 1.6.14 2012/06/04
517 Fix for IE7/8 in pz.js
519 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
521 Lower log level some places.
523 Remove some invalid test results.
525 --- 1.6.13 2012/05/23
527 Introducing a version=2 parameter for show, termlist and bytarget commands.
528 This enables pazpar2 to return approximation on hit and count count when
529 doing record filtering using the limit parameter on search and a
530 limitmap with a value of "local:"
532 Setting pz:xslt may embed local XSLT as an alternative to referring
534 Value is not CDATA but XML nodes embedded, so escaping is not necessary
535 but a root element *must* be present. For example:
536 <settings target="target="z3950.indexdata.com/marc">
545 Metadata field rank may given by XML internal document (pz:xslt
546 result). If rank is not given, the rank from service description is
549 Metadata field can now configured a default limitmap and facetmap.
550 Setting limitmap to "local:" would work for all kind of targets, but would
551 prob. not be the optimal solution. But at least better than the default behavior
552 of pazpar2 where no filtering is done.
554 A service definition can now also contains <set/> that defines service-wide
555 settings. These will override server-wide sets and will be overridded by
558 New setting, pz:present_chunk, that specifies number of records to fetch
559 at a time. Zero will disable chunkation; will fetch max_records at once.
561 --- 1.6.12 2012/03/14
563 Revert the format change in termlist response, that could break
564 some clients / UIs since they were expecting an (empty) element
565 if no facet values was found.
567 --- 1.6.11 2012/03/07
569 Revert the behavior of returning errors when unable to block
570 on termlist, bytarget and search, when unable to block due to
571 other block. The client will now receive a regular response,
572 but it will be logged in the server. A parameter (report) is
573 added to change behavior to return error response or WARNING
574 status message. Consider this "API" as private, as it is mostly
575 untested and could be changed in future releases.
577 Fix spell error in pz2.js fix in 1.6.10.
579 New Marc2TurboMarc.xsl (contribution from Sven Porst).
580 Can solve the missing marc21.xsl updates in some cases.
582 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
583 substring (contribtion from Sven Porst)
585 marc21.xsl: fix 1-based substring call
587 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
589 Add test_termlist_block to test suite
591 --- 1.6.10 2012/02/23
593 Fix SEGV for invalid PQFs and SRU/SOLR targets
594 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
596 Fix pz2.js: "null object" due to change in in bytarget result XML.
598 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
599 Added this normalization to the other subject-long fields (d6xx),
600 where it was missing.
602 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
603 Still differences around medium and holdings. marc21.xsl is not
604 longer active used by Index Data, and should be considered unsupported.
605 Use tmarc.xsl instead.
609 Fix SEGV that could occur for failed connections.
613 Fix bug for command sort that could return no results for active clients
614 (from previous search). This bug was present in 1.6.6-1.6.7.
616 Fix bug in results that could include results that should have been
617 filtered out. This bug was present in 1.6.6-1.6.7.
621 Fix bug introduced in 1.6.6 where a connection re-use could stall
624 Local filtering may now specify a local metadata field, eg.
625 pz:limitmap:somefield[t]=local:otherfield
629 For search, when limit and or filtering is in place and search
630 is identical to previous search, the result set is re-used and the
631 target is not searched.
633 Limits may work perform local filtering as well, by using "local:"
638 Updated bytarget command to contain a suggestions element with misspelled
639 words and suggestions to these. pz2.js has been updated to deliver this
640 onwards as well. Only target that currently delivers this is the solr
641 client in YAZ 4.2.18.
645 New service definition element, xslt, that allows an embedded stylesheet
646 to be defined. This can be referred to from pz:xslt as an alternative to
649 New pz:sortmap:field setting for specifying hints on how to make
650 a target natively sort on a field. This is used for command=show in
651 conjunction with sort.
653 New pz:url setting for specifying the actual URL for a target. When
654 this is used the target ID is not used as URL anymore and the target ID
655 may be almost any string (not including []).
657 command=termlist without name parameter returns all termlists/facets.
658 Previously if name parameter was omitted, only "subject" was returned.
662 Make termlist sorting stable. Terms with same frequency are now sorted by
663 their display name. This makes a pretty display and improves our
664 regression test because qsort is not a stable sort.
666 New sort parameter value 'position'. The 'position' sorts merged records
667 by their original position from the remote target. This is primarily useful
668 for debugging and may be used for targets that already perform some kind
669 of relevance ranking. Note that sort by default is decreasing; so to get
670 records in their original order sort=position:1 must be used.
674 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
676 Facility to change working directory for pazpar2 daemon. Option -wdir
677 sets working directory to dir. This facility is useful if core dumps
678 must be saved. In this case, the current working directory must be
679 writable by the running user, such as "nobody".
683 New configuration element <icu_chain> for <server>/<service> which
684 allows a named ICU rule (chain) to be defined. The names relevance,
685 sort, mergekey and facet are used for those operations. The definition
686 <icu_chain id="sort" locale="en"> .. </icu_chain>
688 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
689 And so on.. for relevance, mergekey and facet as well. The latter
690 style is deprecated. The facet terms are normalized by the facet
691 rule by default. This may be changed on a metadata field basis by
692 defining the new attribute 'facetrule' for the metadata element.
694 <icu_chain id="myrule" locale="en"> ... </icu_chain>
695 <metadata name="author" termlist="yes" facetrule="myrule"/>
697 Preserve rorder for merged metadata. Fixes issue as reported by Sven
698 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
700 tmarc.xsl: set journal-subpart to 773$ only.
704 Modify the behavior for the limit parameter (first defined in 1.5.7).
705 Mapping of limit searches are now defined by the new configuration item
706 pz:limitmap. Fix a dead-lock problem with the limit parameter.
708 Extend tmarc.xsl to extract 773$g data (OpenURL).
712 ICU default maps remove backquote (`).
714 Command 'search' takes limit parameter (optional). The limit parameter
715 allows a search to be limited one or more facets and the corresponding
716 values. This is for server side filtering.
718 Configure tweak: Use -lm for log(3) if needed
722 Fix a problem with skiparticle sortkey that could be completely
723 ignored (and reduced to "").
725 Fix dependency problem in pazpar2 RPM package (did not require
726 libyaz4 as it should).
730 Fix memory leak that occurred for command=termlist&name=xtargets .
732 Pazpar2 may save HTTP requests. Enabled by option -R.
736 Experimental support for DTIC DADS target. New dads-pz2.xsl.
738 Support for query_syntax (overrides the default for SRU | Z39.50)
740 Support for extraArgs (ZOOM "extraArgs" option) for targets
742 New commands: status-server and status-session
746 Fix for threaded runs: Client now have a copy of the database URL,
747 which can used after the database has been release from the client.
748 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
750 tmarc.xsl: Add journal-title-abbrev and full text.
752 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
754 Fix for cmd=record before search.
756 Session Logging clean up.
758 Fix wrong termlist factor when maxrecs is different from 100.
762 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
763 Term factor is default enabled but can be diseabled by
764 pz:termlist_term_factor=0
768 Add scaling of facet count. Currently always enabled, needs fixing.
769 Allow user-defined info for target suffix. This has no meaning in
770 Pazpar2 except to distinguish targets from each other. The suffix
771 data begins with #. For example z3950.indexdata.com/gils#Mydata
773 Added exact-match recordfilter; format name=value
777 SOLR support. Pazpar2 may operate as web service client for SOLR.
781 Fix for show command and block=1 (dead lock). Bug was introduced in
786 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
787 tested on CentOS 5.5 only.
791 Fix problem with result sets being removed from a client session
792 if the connection for it was resused by another session. Bug #3489.
794 New iphone UI for Pazpar2 (www/iphone).
798 Fixes for threaded operation.
800 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
802 New example services in etc/services in source. In the Debian packages
803 these are located in /etc/pazpar2/services-available
805 Threaded mode operational on Windows. Requires Windows 7 or Windows
808 Default value of setting pz:max_connections is 0 which means that there
809 is no limit on number of connections.
813 Pazpar2 may operate in threaded mode. Enabled by element threads in
814 the configuration. See pazpar2_conf for details.
816 New setting setting: pz:max_connections. Setting pz:max_connections is
817 a limit of number of sockets to a host. When this limit is reached,
818 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
819 The client will be marked Client_Error when it can not be searched
820 (other clients in a session may work). If pz:max_connections is not set
821 for a target, a value of 30 will be used. Note: the pz:max_connections
822 will only work in threaded mode.
824 pz2.js: JSON support for show.
826 Debian package: Enable default service, default.xml, before starting
827 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
831 Debian version depends on on libyaz4. Note that Pazpar2 will still
832 compile from source with YAZ 3.
834 Split services into separate files. The example configuration file
835 pazpar2.cfg.dist now includes a default service default.xml (part of
836 etc). And default.xml includes settings/edu.xml. The default.xml file,
837 not to be confused with settings/defaults.xml, is a template for jsdemo
838 and other services. The Debian package installs /etc/pazpar2/server.xml
839 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
840 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
841 The default.xml (from etc) is installed in /etc/pazpar2/services-available
842 and a symlink to it is created from services-enabled. The default.xml
843 service is unnamed and, thus, will be used by jsdemo and test1.
845 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
846 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
850 Support for additional fields in cf.xsl and pazpar2.conf.dist:
851 publisher, available, due, location (=locallocation), callno
852 (=callnumber), thumburl and score.
854 Describe pz:xslt and the auto setting.
856 Move mergekey definition away from the normalization stylesheets and
857 define a mergekey common for all target types in pazpar2.cfg.
859 Code update: Use the Odr_int type for hit counts. This is part of
860 YAZ 3.0.47 and later and so configure checks for that.
864 Metadata attribute 'skiparticle' also works for ICU based
865 normalization. (was only working for the non-ICU/ASCII before).
867 Command bytarget with argument settings=1 will show settings per
868 target.. This is to be able to verify correct settings and be able to
869 test that they are correct. The database settings array size is now
870 also stored.. Problems with database settings array is that if not
871 careful it will be too small (smaller than dictionary per-service
874 Make record list sorting stable by comparing mergekey for records if
875 relevance/title or other sorting criteria all match. This is merely to
876 ensure that our regressions tests works (reproducible output).
878 Relevance calculation changes: use a different denominator (length) for
879 per-field relevance scoring.. Instead of length of all ranked fields we
880 now use length of individual fields (as if they were individual "free"
881 text fields). This will ensure that documents with a long field with no
882 match (say description) will not "hurt" a title match.
884 Diagnostic member was not set on connection error. Fixed
888 Command search takes two optional parameters, startecs and maxrecs,
889 that specifies the start offset (0, 1, ...) and maximum number of records
890 to fetch for each target.
892 XSLTs + MARC maps are cached within a session so we don't re-parse
893 them over and over again. Even for a session with a single search
894 there's much to be gained because many targets use the same
897 The metadata attribute 'mergekey' now takes one of three values 'no',
898 'required', 'optional' . And the resulting mergekey from metadata
899 is now ordered in the same way as metadata in the service definition.
900 Older Pazpar2 version use the order in which metadata appeared in a
903 The search argument 'filter' now offers a new operator ~ which does a
904 substring match. The = operator works as before: string match for
905 anything but pz:id, or target match for pz:id.
907 New setting pz:recordfilter. The value of this setting takes the
908 form name[~value]. This setting makes Pazpar2 ignore all retrieved
909 records that do not have the metadata element name with value substring
912 Pazpar2 allows YAZ log level to be set (option -v).
916 For WS responses Pazpar2 creates XML header. Exception: raw record.
918 Setting XML files are now stored in etc/settings instead of etc. This
919 reflects the layout with the Debian package layout.
921 Settings may be posted for command=settings. The POSTed settings must
922 have root element 'settings' like regular setting files. In order to be
923 recognized, the POST request must use Content-Type=text/xml.
925 A service may be posted for command=init. This service will be used
926 during the session. The service may have its own target settings,
927 ICU config, timeout, etc. In order to be recognized, the POST request
928 must use Content-Type=text/xml.
930 Timeout values may be given per-service. That's element 'timeout'
931 which takes three attribute values (a subset may be given): 'session',
932 'z3950_operation', 'z3950_session'. Option -T is no longer supported
933 - used to specify session timeout.
935 Option -t tests the Pazpar2 configuration and returns exit code
936 (0=success, non-zero=failure). In previous version of Pazpar2, -t
937 specified local settings.
939 In version 1.2.0 the configuration file - after include processing -
940 was dumped to stdout. Now, the configuration is only dumped to the
941 yaz log file if option -d is given.
945 Configuration may now have multiple server areas. This means that a
946 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
947 yet supported - on a server basis. Configuration may also have multiple
948 services .. That is repeating service elements inside a server. Each
949 has an attribute 'id' which serves as service ID. This ID in turn may
950 be used in a Pazpar2 session, by specifying parameter service=ID for
951 command init. There can be at most one unnamed service inside a server
952 which can be referred to by not specifying an service ID for command
953 init (backwards compatible). In order to partition multiple servers and
954 services a new include directive has been added. This takes an attribute
955 'src' which specifies one or more sub-files. For example to include
956 service files, one might use:
957 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
958 It is the intention that that completely makes the settings directive
961 Fix problem where the record command would wait forever if there were
962 no targets to wait for (activeclients == 0).
966 One result set is created per session (last search) rather than for
967 each connection which happen to be shared (bug #3009).
969 marc21 stylesheets changed for efficiency.
973 Session timeout may be specified on the command-line as option -T.
975 Pazpar2 may now be operated in a no-merged mode for records.. All records
976 will be considered unique. This mode is enabled if no mergekey is
977 generated by the normalization stylesheet (pz:xslt).
979 Pazpar2 caches original records from each target and the 'record' command
980 with offset returns the original record if 'syntax' and 'esn' are NOT
981 specified. This speeds up retrieval of original records but also means
982 that Pazpar2 uses more memory. The cached records will be freed when the
983 session terminates or a new search is executed.
985 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
986 library part of YAZ is used.
988 Added SRU client support.
990 Automatically computes pz:nativesyntax if not provided. Works for XML and
993 --- 1.0.13 2008/11/24

1040 Added support for retrieval of records in binary.
1042 Fixed bug 1794: Pazpar2 does not return valid XML.
1044 Deal with ICU not returning sortkey (resulted in SEGV before).
1046 --- 1.0.4 2007/09/28
1048 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1049 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1051 Improved diagnostics when Pazpar2 HTTP decoding fails.
1053 Pazpar2 requests may be POSTed as using Content-Type
1054 application/x-www-form-urlencoded.
1056 Pazpar2 honors LF in HTTP headers.
1058 Handle targets that handle negative hit counts (should not happen, but it
1061 --- 1.0.3 2007/09/19
1063 ICU is used for tokenization and normalization of the following: mergekey,
1064 sorting, relevance terms.
1066 Debian package now enables ICU tokenization and normalization by default.
1068 --- 1.0.2 2007/08/22
1070 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1071 ways: Either as parameters to the normalization stylesheets (which would allow the
1072 programmer to postprocess or use the values in any way) or after the normalization
1073 step, in which case values are made part of the normalized record (and available for
1074 sorting, termlists, display, or other interface-related use.
1076 Implemented sorting by year.
1078 Option -d dumps records to the current log file instead of stderr.
1080 Fixes for compilation on cygwin.
1082 Z39.50 client code uses pz:elements. pz:elements was recognized in
1083 earlier Pazpar2 versions but it was not used for anything.
1085 icu_chain_test is using fgets instead of getline - fixes compilation
1088 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1089 query conversions fail (rather than _any_). This means targets that do
1090 not support some fields are ignored in a search.
1092 --- 1.0.1 2007/07/03
1094 Improved handling of socket timeout for Z39.50 connections.
1096 Misc documentation updates and spell fixes.
