9 Allow multiple updates within one transaction.
11 Fixed a bug with >2GB files (overflow in integer expression).
15 Fix linker error for Perl module.
17 Fix bug in and operation which in some cases could result in "extra"
18 hits. Bug was introduced in 1.3.5.
20 Fix bug in handling of schema conversion when producing numeric tags.
26 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
30 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and

39 Advanced MARC indexing. See doc/marc_indexing.xml
40 Oleg Kolobov <oleg at lib.tpu.ru>
42 Perl API updates and fixes.
43 Peter Popovics <pop at technomat.hu>
45 Fixed 'zebraidx delete'.
47 Implemented 'zebraidx clean'.
49 64-bit offsets for register files on WIN32 (no 2 GB limit).
51 Fixed a few memory leaks WRT sorting.
55 Fixed error handling : error code was not properly returned.
57 Support Truncation 104 (CCL).
61 Added missing source files for perl extension.
65 Implemented xelm directive.
67 Updated for newer version of YAZ (introduction of string schema).
69 Directory examples/zthes now part of distribution (was missing
72 New .abs directive, systag, that control where to put retrieval
73 information. The directive takes two arguments: system tag, element name.
74 System tag is one of : rank, sysno, size.
78 Perl Filter and Perl API. By Peter Popovics.
80 For zebra.cfg, if no profilePath is specified, directory
81 (prefix)/share/idzebra/tab
84 Zebra Examples in examples . Zebra tests in test.
86 Bug fix: sort index was not properly modified on
87 record updates/deletes.
89 Fix handling of character entities for sgml filter.
91 Move data1 to Zebra (used to be part of YAZ).
95 Fix character encoding of scan response terms.
97 Fix character decoding of scan request terms.
99 Fix ESpec handling (requires YAZ 1.9.1)
101 Fix searches for complete fields.
105 When name zebra is used in a filename or directory 'idzebra' is used
106 instead to avoid confusion with GNU zebra (routing software).
108 Zebra server stops with a fatal error if config file cannot be read.
110 New config setting, followLinks, that controls whether update of files
111 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
112 By default symbolic links are followed.
114 Fix MARC transfer . MARC fields had wrong data for multiple fields.
116 XML record reader moved from YAZ to Zebra, to make YAZ less
117 dependant on external libraries.
119 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
120 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
121 on systems that doesn't offer iconv.
123 XML record reader supports external system entities.
127 New .abs-directive "xpath" that takes one argument: "enable"
128 or "disable" to enable and disable XPath -indexing. If no "xpath"
129 direcive is found in .abs-file , XPath-indexing is disabled to ensure
130 backwards compatibility. For missing .abs-files XPath-indexing is
131 enabled so that such records are searchable.
133 Zebra warns about missing .abs-file only once (for each type).
135 Fixed a bug in file update where already-inserted files could
140 Zebra license changed to GNU GPL.
142 XPath-like queries used when RPN string attributes are used, eg.
143 @attr 1=/portal/title sometitle
144 @attr 1=/portal/title[@xml:lang=da] danishtitle
145 @attr 1=/portal/title/@xml:lang da
146 @attr 1=//title sometitle
148 Zebra uses UTF-8 internally:
149 1) New setting "encoding" for zebra.cfg that specifies encoding for
150 OCTET terms in queries and record encoding for most transfer syntaxes
151 (except those that use International Strings, such as GRS-1).
152 2) The encoding of International strings is UTF-8 by default. It
153 may be changed by character set negotiation. If character set
154 negotiation is in effect and if records are selected for conversion
155 these'll be converted to the selected character set - thus overriding
156 the encoding setting in zebra.cfg.
157 3) New directive "encoding" in .abs-files. This specifies the external
158 character encoding for files indexed by zebra. However, if records
159 themselves have an XML header that specifies and encoding that'll be used
162 XML filter (-t grs.xml).
164 Multiple registers. New setting in resource 'root' that holds base
165 directory for register(s). A group a databases may be put in separate
166 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
170 Fixes for Digital Unix
172 Implemented hits per term using USR:SearchResult-1.
174 New Zebra API. Locking system re-implemented.
176 --- 1.1.stable 2002/02/20
178 Rank weight can be controlled with attribute type 9. Default
179 value is 34. Recommended values between 1-36.
183 Updated for YAZ version 1.8.
185 Added support for termsets - a result set of terms matching
186 a given query. For @attr 8=<set> creates termset named <set>.
188 Added support for raw retrieval. Element Set Name R forces the
189 text filter which returns the record in its original form.
191 Added numerical sort - triggered by structure=numeric (4=109).
193 Remote record import using Z39.50 Extended Services and Segments.
195 Fixed bug where updating a database with user-defined attributes
196 could corrupt the register (bad storeKeys).
198 Multi-threaded version.
200 Fixed bug regarding proximity.
202 Documentation updates.
204 Fixed bug in record retrieval module that occured on 64-bit OSF
209 Fixed bug in makefile for WIN32.
211 Fixed bug in configure script - used bash-specific features.
215 Added support for multiple records in one file for filter grs.sgml.
217 Changed record index structure. New layout is incompatible with
218 previous releases. Added setting "recordcompression" to control
219 compression of records. Possible values are "none" (no
220 compression) and bzip2 (compression using libbz2).
222 Added XML transfer syntax support for retrieval of structured records.
223 Schema in CompSpec is recognised in retrieval of structured records.
225 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
226 that fails, the filter reads the file <filt>.flt (regx style filter).
228 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
229 Zebra's configure script automatically attempts to locate Tcl. For
230 manual Tcl configuration use option --with-tclconfig=<path> to specify
231 where Tcl's library files are located.
233 Implemented "compression" of Dictionary and ISAM system. Dictionary
236 Added "tagsysno" directive to zebra.cfg to control under which tag the
237 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
240 Added "tagrank" as above.
242 Changed file naming scheme for register files from <name>.mf.<no> to
245 Implemented "position"-flag for register type (as defined in
246 default.idx). When set to zero no position (or seqence number) is
247 saved in register for each word occurrence, thus saving some register
250 Implemented database mapping. Using mapdb one can specify a database
251 to be mapped to one or more physical databases. Usage:
252 mapdb <fromdb> <todb> ..
254 Added SOIF-filter. Thanks to Peter Valkenburg.
256 For the regx-filter "end element -record" may trigger a mark-of-record
257 if outer level is reached.
259 Tag sets may be typed in the reference to it. From the .abs-file the
260 "tagset" directive takes a third optional integer type for the tag set
261 referenced. From a .tag-file the "include" directive takes a third
262 optional type as well. The old "type" directive in the tag set itself
263 is still recognized but acts as the default type for the tag set.
265 Zebra supports the specification of arbitrary attributes sets, schemas
266 and tag sets, because of the change in YAZ' OID management system.
268 Fixed bug in Sort that caused it NOT to use character mapping as it
271 Zebra now uses GNU configure to generate Makefile(s).
273 Added un-optimised support for left and left/right truncation attributes.
275 Added support for relational operators on text when using RPN queries.
277 Added support for sort specifications in RPN queries. Type 7 specifies
278 'sort' where value 1=ascending, value 2=descending. The use attribute
279 specifies the field criteria as usual. The term specifies priority
280 where 0=first, 1=second, ...
282 Changed the way use attributes are specified in the recordId
285 Maximum number of databases in one Zebra register increased.
287 New setting, databasePath, which specifies that first directory during
288 update traversal is the database name (instead of a fixed one).
290 New setting, explainDatabase, which specifies that databases are
293 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
295 Implemented EXPLAIN database maintenance. Zebra automatically
296 generate - and update CategoryList, TargetInfo, DatabaseInfo,
297 AttributeSetInfo and AttributeDetails records at this stage. The
298 records may be transferred as GRS-1, SUTRS or Explain.
300 Fixed register spec so that colon isn't treated as size separator
301 unless followed by [0-9+-] in order to allow DOS drive specifications.
303 Fixed two bugs in ISAMC system.
305 Changed the way Zebra keeps its maintenance information about attribute
306 sets, available attributes, etc.. Records in "SGML" notation using an
307 EXPLAIN schema is now used when appropriate.
309 Bug fix: Index didn't handle update/insert/delete of the same record
310 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
311 first occurence of a record is considered.
313 Most searches now return correct number of hits.
315 New modular ranking system. Interested programmers are encouraged to
316 inspect rank1.c and improve the algorithm.
318 Bug fix: Lock files weren't removed as they should on NT.
320 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
321 specify a "sort register". Refer to the gils sample records which refer
322 to index type "s" which is specified as "sort" in the default.idx file.
323 Each sort criteria can either be Ascending or Descending and at most
324 three sort elements can be specified.
326 Bug fix: Character mapping didn't work for text files.
330 Simple ranked searches now return correct number of hits.
332 The test option (-s) only makes a read-lock on the index as well
333 as using read-only operations anywhere.
335 Moved towards generic character mapping. Configuration file default.idx
336 specifies character map files for register types w, p, u, etc.
338 Implemented "begin variant" for the sgml.regx - filter.
340 Fixed a few memory leaks.
342 Added support for C++, headers uses extern "C" for public definitions.
344 Bug fix: The show records facility (-s) only displayed information for
345 the first record in a file (and not for every record in the file).
347 Added option "-f <n>" to limit the logging of record operations. After
348 <n> records has been processed no logging is performed (unless errors
351 Bug fix: the compressed ISAM system didn't handle update operations
354 Added setting, "maxResultSetSize", to hold the number of records to
355 save in a result set.
357 Bug fix: Complete phrase did't work for search operations.
359 Bug fix: temporary result sets weren't deleted.
361 Reduced disk space for saved keys (storeKeys = 1).
363 Added optional, physical ANY (key replication)
365 Implemented proximity operator in search.
367 Bug fix: the path name buffers used by file match traversal routines
368 have been extended to support long file names.
370 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
371 configuration file. The resulting register without "storeKeys" is about
372 half the size, and the memory used by zebraidx during phase 2 (merge) is
373 reduced to a minimum.
375 Reworked the way Regexp-2 queries with error tolerance are handled and
376 specified. The documentation has been updated accordingly.
378 Bug fix: Zebrasrv didn't search correctly when queries contained masking
379 characters. This bug was introduced in 1.0a8.
381 Zebrasrv now tag records with the proper database name.
383 New settings, memMax and keyTmpDir.
385 Changed name of setting lockDir (previously called lockPath) and
386 setTmpDir (previously called tempSetPath).
388 Generalized and changed record type specifications. In short, there are:
390 grs.sgml structured, "SGML-like" syntax
391 grs.regx.<filter> structured, Regular expression filter
392 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
393 is the name of an abstract syntax file.
394 Bug fix: Result sets weren't sorted in operations involving boolean
395 operations with "ranked" operands.
399 Added national character-handling subsystem.
403 Small modifications to input filters and profiles.
405 Added support for SOIF syntax (with private OID).
409 Fixed buffer-size problem in indexing.
411 Added compression to temporary files for updating.
413 Added phrase registers.
415 Added dynamic mapping of search attribute to multiple termlists (ANY).
417 Scan support in multiple databases/registers.
419 Configuration settings are case-insensitive and single dash (-)
420 characters are ignored in comparisons.
422 The index processing ignores empty files - warning given.
424 New option to zebraidx (-V) displays version information.
428 Fixed problem in file-update system.
430 Fixed problem in shadow system; register was sometimes corrupted after
435 Fixed problems in the ISAM subsystem. Caused difficulties when updating
438 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
439 the rank and record number.
441 Fixed bug in the isam subsystem - caused a malfunction when accessing
442 words which occurred more than 10000 times.
444 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
447 Server can now run under inetd. Use option -i, and -w <directory> to
448 set working directory to desired location.
450 New zebraidx command: clean - removes temporary shadow files.
452 Fixed bug in ISAM system. Occurred rarely during register updates.
454 Logging during index merge phase is improved. The remaining running
457 Temporary files generated by zebraidx are removed after each run.
459 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
460 when doing scan operations in dictionaries with European characters.
464 A whole slew of updates, to make the first publicized release. Get the doc
469 Memory-problems in ISAM fixed. More blocktypes added to the default setup
470 to increase performance on larger databases.
472 Various minor changes in data management system.
476 A couple of portability-problems resolved.
478 Changed some malloc() to xmalloc().
