11 Fix bug in regx filter to make it "greedy" again. This bug appeared
18 Fix XML error handling. Stop XML parse immediately if XML parse error
19 occur (i.e. produce one error only).
21 Zebra ignores "unsupported use attribute" for individual databases
22 when search multiple databases (unless all databases fail).
24 New filter grs.marcxml which works like grs.marc but produces MARCXML.
26 Added support for database deletion. It is possible to create/drop
27 a database from zebraidx utility. Note: only for isam:b.
29 Write zebrasrv.pid to lockdir.
31 Bug fix: result sets were not recovered correctly. Had to
32 add ODR handle for zebra_search_RPN in order to make it work.
34 Fixed a bug in regx filters that didn't do anchors (^) correctly.
36 Fixed a bug in searches with X-Path searches sometimes giving "extra"
39 Zebra server checks for zebrasrv.pid and refuses to start if it is already
40 locked by another (running) zebrasrv.
42 Fixed a bug with text being chunked in pieces for the grs.xml filter.
46 xelm code updates. xelm works regardless state of 'xpath enable/disable'

49 Allow multiple updates within one transaction.
51 Fixed a bug with >2GB files (overflow in integer expression).
55 Fix linker error for Perl module.
57 Fix bug in and operation which in some cases could result in "extra"
58 hits. Bug was introduced in 1.3.5.
60 Fix bug in handling of schema conversion when producing numeric tags.
66 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
70 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
71 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
72 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
74 livrank: another experimental ranking algorithm. Source in livcode.c.
75 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
77 Contributed by Pete Mallinson, University of Liverpool.
79 Advanced MARC indexing. See doc/marc_indexing.xml
80 Oleg Kolobov <oleg at lib.tpu.ru>
82 Perl API updates and fixes.
83 Peter Popovics <pop at technomat.hu>
85 Fixed 'zebraidx delete'.
87 Implemented 'zebraidx clean'.
89 64-bit offsets for register files on WIN32 (no 2 GB limit).
91 Fixed a few memory leaks WRT sorting.
95 Fixed error handling : error code was not properly returned.
97 Support Truncation 104 (CCL).
101 Added missing source files for perl extension.
105 Implemented xelm directive.
107 Updated for newer version of YAZ (introduction of string schema).
109 Directory examples/zthes now part of distribution (was missing
110 in previous release).
112 New .abs directive, systag, that control where to put retrieval
113 information. The directive takes two arguments: system tag, element name.
114 System tag is one of : rank, sysno, size.
118 Perl Filter and Perl API. By Peter Popovics.
120 For zebra.cfg, if no profilePath is specified, directory
121 (prefix)/share/idzebra/tab
124 Zebra Examples in examples . Zebra tests in test.
126 Bug fix: sort index was not properly modified on
127 record updates/deletes.
129 Fix handling of character entities for sgml filter.
131 Move data1 to Zebra (used to be part of YAZ).
135 Fix character encoding of scan response terms.
137 Fix character decoding of scan request terms.
139 Fix ESpec handling (requires YAZ 1.9.1)
141 Fix searches for complete fields.
145 When name zebra is used in a filename or directory 'idzebra' is used
146 instead to avoid confusion with GNU zebra (routing software).
148 Zebra server stops with a fatal error if config file cannot be read.
150 New config setting, followLinks, that controls whether update of files
151 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
152 By default symbolic links are followed.
154 Fix MARC transfer . MARC fields had wrong data for multiple fields.
156 XML record reader moved from YAZ to Zebra, to make YAZ less
157 dependant on external libraries.
159 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
160 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
161 on systems that doesn't offer iconv.
163 XML record reader supports external system entities.
167 New .abs-directive "xpath" that takes one argument: "enable"
168 or "disable" to enable and disable XPath -indexing. If no "xpath"
169 direcive is found in .abs-file , XPath-indexing is disabled to ensure
170 backwards compatibility. For missing .abs-files XPath-indexing is
171 enabled so that such records are searchable.
173 Zebra warns about missing .abs-file only once (for each type).
175 Fixed a bug in file update where already-inserted files could
180 Zebra license changed to GNU GPL.
182 XPath-like queries used when RPN string attributes are used, eg.
183 @attr 1=/portal/title sometitle
184 @attr 1=/portal/title[@xml:lang=da] danishtitle
185 @attr 1=/portal/title/@xml:lang da
186 @attr 1=//title sometitle
188 Zebra uses UTF-8 internally:
189 1) New setting "encoding" for zebra.cfg that specifies encoding for
190 OCTET terms in queries and record encoding for most transfer syntaxes
191 (except those that use International Strings, such as GRS-1).
192 2) The encoding of International strings is UTF-8 by default. It
193 may be changed by character set negotiation. If character set
194 negotiation is in effect and if records are selected for conversion
195 these'll be converted to the selected character set - thus overriding
196 the encoding setting in zebra.cfg.
197 3) New directive "encoding" in .abs-files. This specifies the external
198 character encoding for files indexed by zebra. However, if records
199 themselves have an XML header that specifies and encoding that'll be used
202 XML filter (-t grs.xml).
204 Multiple registers. New setting in resource 'root' that holds base
205 directory for register(s). A group a databases may be put in separate
206 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
210 Fixes for Digital Unix
212 Implemented hits per term using USR:SearchResult-1.
214 New Zebra API. Locking system re-implemented.
216 --- 1.1.stable 2002/02/20
218 Rank weight can be controlled with attribute type 9. Default
219 value is 34. Recommended values between 1-36.
223 Updated for YAZ version 1.8.
225 Added support for termsets - a result set of terms matching
226 a given query. For @attr 8=<set> creates termset named <set>.
228 Added support for raw retrieval. Element Set Name R forces the
229 text filter which returns the record in its original form.
231 Added numerical sort - triggered by structure=numeric (4=109).
233 Remote record import using Z39.50 Extended Services and Segments.
235 Fixed bug where updating a database with user-defined attributes
236 could corrupt the register (bad storeKeys).
238 Multi-threaded version.
240 Fixed bug regarding proximity.
242 Documentation updates.
244 Fixed bug in record retrieval module that occured on 64-bit OSF
249 Fixed bug in makefile for WIN32.
251 Fixed bug in configure script - used bash-specific features.
255 Added support for multiple records in one file for filter grs.sgml.
257 Changed record index structure. New layout is incompatible with
258 previous releases. Added setting "recordcompression" to control
259 compression of records. Possible values are "none" (no
260 compression) and bzip2 (compression using libbz2).
262 Added XML transfer syntax support for retrieval of structured records.
263 Schema in CompSpec is recognised in retrieval of structured records.
265 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
266 that fails, the filter reads the file <filt>.flt (regx style filter).
268 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
269 Zebra's configure script automatically attempts to locate Tcl. For
270 manual Tcl configuration use option --with-tclconfig=<path> to specify
271 where Tcl's library files are located.
273 Implemented "compression" of Dictionary and ISAM system. Dictionary
276 Added "tagsysno" directive to zebra.cfg to control under which tag the
277 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
280 Added "tagrank" as above.
282 Changed file naming scheme for register files from <name>.mf.<no> to
285 Implemented "position"-flag for register type (as defined in
286 default.idx). When set to zero no position (or seqence number) is
287 saved in register for each word occurrence, thus saving some register
290 Implemented database mapping. Using mapdb one can specify a database
291 to be mapped to one or more physical databases. Usage:
292 mapdb <fromdb> <todb> ..
294 Added SOIF-filter. Thanks to Peter Valkenburg.
296 For the regx-filter "end element -record" may trigger a mark-of-record
297 if outer level is reached.
299 Tag sets may be typed in the reference to it. From the .abs-file the
300 "tagset" directive takes a third optional integer type for the tag set
301 referenced. From a .tag-file the "include" directive takes a third
302 optional type as well. The old "type" directive in the tag set itself
303 is still recognized but acts as the default type for the tag set.
305 Zebra supports the specification of arbitrary attributes sets, schemas
306 and tag sets, because of the change in YAZ' OID management system.
308 Fixed bug in Sort that caused it NOT to use character mapping as it
311 Zebra now uses GNU configure to generate Makefile(s).
313 Added un-optimised support for left and left/right truncation attributes.
315 Added support for relational operators on text when using RPN queries.
317 Added support for sort specifications in RPN queries. Type 7 specifies
318 'sort' where value 1=ascending, value 2=descending. The use attribute
319 specifies the field criteria as usual. The term specifies priority
320 where 0=first, 1=second, ...
322 Changed the way use attributes are specified in the recordId
325 Maximum number of databases in one Zebra register increased.
327 New setting, databasePath, which specifies that first directory during
328 update traversal is the database name (instead of a fixed one).
330 New setting, explainDatabase, which specifies that databases are
333 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
335 Implemented EXPLAIN database maintenance. Zebra automatically
336 generate - and update CategoryList, TargetInfo, DatabaseInfo,
337 AttributeSetInfo and AttributeDetails records at this stage. The
338 records may be transferred as GRS-1, SUTRS or Explain.
340 Fixed register spec so that colon isn't treated as size separator
341 unless followed by [0-9+-] in order to allow DOS drive specifications.
343 Fixed two bugs in ISAMC system.
345 Changed the way Zebra keeps its maintenance information about attribute
346 sets, available attributes, etc.. Records in "SGML" notation using an
347 EXPLAIN schema is now used when appropriate.
349 Bug fix: Index didn't handle update/insert/delete of the same record
350 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
351 first occurence of a record is considered.
353 Most searches now return correct number of hits.
355 New modular ranking system. Interested programmers are encouraged to
356 inspect rank1.c and improve the algorithm.
358 Bug fix: Lock files weren't removed as they should on NT.
360 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
361 specify a "sort register". Refer to the gils sample records which refer
362 to index type "s" which is specified as "sort" in the default.idx file.
363 Each sort criteria can either be Ascending or Descending and at most
364 three sort elements can be specified.
366 Bug fix: Character mapping didn't work for text files.
370 Simple ranked searches now return correct number of hits.
372 The test option (-s) only makes a read-lock on the index as well
373 as using read-only operations anywhere.
375 Moved towards generic character mapping. Configuration file default.idx
376 specifies character map files for register types w, p, u, etc.
378 Implemented "begin variant" for the sgml.regx - filter.
380 Fixed a few memory leaks.
382 Added support for C++, headers uses extern "C" for public definitions.
384 Bug fix: The show records facility (-s) only displayed information for
385 the first record in a file (and not for every record in the file).
387 Added option "-f <n>" to limit the logging of record operations. After
388 <n> records has been processed no logging is performed (unless errors
391 Bug fix: the compressed ISAM system didn't handle update operations
394 Added setting, "maxResultSetSize", to hold the number of records to
395 save in a result set.
397 Bug fix: Complete phrase did't work for search operations.
399 Bug fix: temporary result sets weren't deleted.
401 Reduced disk space for saved keys (storeKeys = 1).
403 Added optional, physical ANY (key replication)
405 Implemented proximity operator in search.
407 Bug fix: the path name buffers used by file match traversal routines
408 have been extended to support long file names.
410 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
411 configuration file. The resulting register without "storeKeys" is about
412 half the size, and the memory used by zebraidx during phase 2 (merge) is
413 reduced to a minimum.
415 Reworked the way Regexp-2 queries with error tolerance are handled and
416 specified. The documentation has been updated accordingly.
418 Bug fix: Zebrasrv didn't search correctly when queries contained masking
419 characters. This bug was introduced in 1.0a8.
421 Zebrasrv now tag records with the proper database name.
423 New settings, memMax and keyTmpDir.
425 Changed name of setting lockDir (previously called lockPath) and
426 setTmpDir (previously called tempSetPath).
428 Generalized and changed record type specifications. In short, there are:
430 grs.sgml structured, "SGML-like" syntax
431 grs.regx.<filter> structured, Regular expression filter
432 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
433 is the name of an abstract syntax file.
434 Bug fix: Result sets weren't sorted in operations involving boolean
435 operations with "ranked" operands.
439 Added national character-handling subsystem.
443 Small modifications to input filters and profiles.
445 Added support for SOIF syntax (with private OID).
449 Fixed buffer-size problem in indexing.
451 Added compression to temporary files for updating.
453 Added phrase registers.
455 Added dynamic mapping of search attribute to multiple termlists (ANY).
457 Scan support in multiple databases/registers.
459 Configuration settings are case-insensitive and single dash (-)
460 characters are ignored in comparisons.
462 The index processing ignores empty files - warning given.
464 New option to zebraidx (-V) displays version information.
468 Fixed problem in file-update system.
470 Fixed problem in shadow system; register was sometimes corrupted after
475 Fixed problems in the ISAM subsystem. Caused difficulties when updating
478 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
479 the rank and record number.
481 Fixed bug in the isam subsystem - caused a malfunction when accessing
482 words which occurred more than 10000 times.
484 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
487 Server can now run under inetd. Use option -i, and -w <directory> to
488 set working directory to desired location.
490 New zebraidx command: clean - removes temporary shadow files.
492 Fixed bug in ISAM system. Occurred rarely during register updates.
494 Logging during index merge phase is improved. The remaining running
497 Temporary files generated by zebraidx are removed after each run.
499 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
500 when doing scan operations in dictionaries with European characters.
504 A whole slew of updates, to make the first publicized release. Get the doc
509 Memory-problems in ISAM fixed. More blocktypes added to the default setup
510 to increase performance on larger databases.
512 Various minor changes in data management system.
516 A couple of portability-problems resolved.
518 Changed some malloc() to xmalloc().
