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

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

86 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
88 livrank: another experimental ranking algorithm. Source in livcode.c.
89 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
91 Contributed by Pete Mallinson, University of Liverpool.
93 Advanced MARC indexing. See doc/marc_indexing.xml
94 Oleg Kolobov <oleg at lib.tpu.ru>
96 Perl API updates and fixes.
97 Peter Popovics <pop at technomat.hu>
99 Fixed 'zebraidx delete'.
101 Implemented 'zebraidx clean'.
103 64-bit offsets for register files on WIN32 (no 2 GB limit).
105 Fixed a few memory leaks WRT sorting.
109 Fixed error handling : error code was not properly returned.
111 Support Truncation 104 (CCL).
115 Added missing source files for perl extension.
119 Implemented xelm directive.
121 Updated for newer version of YAZ (introduction of string schema).
123 Directory examples/zthes now part of distribution (was missing
124 in previous release).
126 New .abs directive, systag, that control where to put retrieval
127 information. The directive takes two arguments: system tag, element name.
128 System tag is one of : rank, sysno, size.
132 Perl Filter and Perl API. By Peter Popovics.
134 For zebra.cfg, if no profilePath is specified, directory
135 (prefix)/share/idzebra/tab
138 Zebra Examples in examples . Zebra tests in test.
140 Bug fix: sort index was not properly modified on
141 record updates/deletes.
143 Fix handling of character entities for sgml filter.
145 Move data1 to Zebra (used to be part of YAZ).
149 Fix character encoding of scan response terms.
151 Fix character decoding of scan request terms.
153 Fix ESpec handling (requires YAZ 1.9.1)
155 Fix searches for complete fields.
159 When name zebra is used in a filename or directory 'idzebra' is used
160 instead to avoid confusion with GNU zebra (routing software).
162 Zebra server stops with a fatal error if config file cannot be read.
164 New config setting, followLinks, that controls whether update of files
165 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
166 By default symbolic links are followed.
168 Fix MARC transfer . MARC fields had wrong data for multiple fields.
170 XML record reader moved from YAZ to Zebra, to make YAZ less
171 dependant on external libraries.
173 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
174 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
175 on systems that doesn't offer iconv.
177 XML record reader supports external system entities.
181 New .abs-directive "xpath" that takes one argument: "enable"
182 or "disable" to enable and disable XPath -indexing. If no "xpath"
183 direcive is found in .abs-file , XPath-indexing is disabled to ensure
184 backwards compatibility. For missing .abs-files XPath-indexing is
185 enabled so that such records are searchable.
187 Zebra warns about missing .abs-file only once (for each type).
189 Fixed a bug in file update where already-inserted files could
194 Zebra license changed to GNU GPL.
196 XPath-like queries used when RPN string attributes are used, eg.
197 @attr 1=/portal/title sometitle
198 @attr 1=/portal/title[@xml:lang=da] danishtitle
199 @attr 1=/portal/title/@xml:lang da
200 @attr 1=//title sometitle
202 Zebra uses UTF-8 internally:
203 1) New setting "encoding" for zebra.cfg that specifies encoding for
204 OCTET terms in queries and record encoding for most transfer syntaxes
205 (except those that use International Strings, such as GRS-1).
206 2) The encoding of International strings is UTF-8 by default. It
207 may be changed by character set negotiation. If character set
208 negotiation is in effect and if records are selected for conversion
209 these'll be converted to the selected character set - thus overriding
210 the encoding setting in zebra.cfg.
211 3) New directive "encoding" in .abs-files. This specifies the external
212 character encoding for files indexed by zebra. However, if records
213 themselves have an XML header that specifies and encoding that'll be used
216 XML filter (-t grs.xml).
218 Multiple registers. New setting in resource 'root' that holds base
219 directory for register(s). A group a databases may be put in separate
220 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
224 Fixes for Digital Unix
226 Implemented hits per term using USR:SearchResult-1.
228 New Zebra API. Locking system re-implemented.
230 --- 1.1.stable 2002/02/20
232 Rank weight can be controlled with attribute type 9. Default
233 value is 34. Recommended values between 1-36.
237 Updated for YAZ version 1.8.
239 Added support for termsets - a result set of terms matching
240 a given query. For @attr 8=<set> creates termset named <set>.
242 Added support for raw retrieval. Element Set Name R forces the
243 text filter which returns the record in its original form.
245 Added numerical sort - triggered by structure=numeric (4=109).
247 Remote record import using Z39.50 Extended Services and Segments.
249 Fixed bug where updating a database with user-defined attributes
250 could corrupt the register (bad storeKeys).
252 Multi-threaded version.
254 Fixed bug regarding proximity.
256 Documentation updates.
258 Fixed bug in record retrieval module that occured on 64-bit OSF
263 Fixed bug in makefile for WIN32.
265 Fixed bug in configure script - used bash-specific features.
269 Added support for multiple records in one file for filter grs.sgml.
271 Changed record index structure. New layout is incompatible with
272 previous releases. Added setting "recordcompression" to control
273 compression of records. Possible values are "none" (no
274 compression) and bzip2 (compression using libbz2).
276 Added XML transfer syntax support for retrieval of structured records.
277 Schema in CompSpec is recognised in retrieval of structured records.
279 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
280 that fails, the filter reads the file <filt>.flt (regx style filter).
282 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
283 Zebra's configure script automatically attempts to locate Tcl. For
284 manual Tcl configuration use option --with-tclconfig=<path> to specify
285 where Tcl's library files are located.
287 Implemented "compression" of Dictionary and ISAM system. Dictionary
290 Added "tagsysno" directive to zebra.cfg to control under which tag the
291 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
294 Added "tagrank" as above.
296 Changed file naming scheme for register files from <name>.mf.<no> to
299 Implemented "position"-flag for register type (as defined in
300 default.idx). When set to zero no position (or seqence number) is
301 saved in register for each word occurrence, thus saving some register
304 Implemented database mapping. Using mapdb one can specify a database
305 to be mapped to one or more physical databases. Usage:
306 mapdb <fromdb> <todb> ..
308 Added SOIF-filter. Thanks to Peter Valkenburg.
310 For the regx-filter "end element -record" may trigger a mark-of-record
311 if outer level is reached.
313 Tag sets may be typed in the reference to it. From the .abs-file the
314 "tagset" directive takes a third optional integer type for the tag set
315 referenced. From a .tag-file the "include" directive takes a third
316 optional type as well. The old "type" directive in the tag set itself
317 is still recognized but acts as the default type for the tag set.
319 Zebra supports the specification of arbitrary attributes sets, schemas
320 and tag sets, because of the change in YAZ' OID management system.
322 Fixed bug in Sort that caused it NOT to use character mapping as it
325 Zebra now uses GNU configure to generate Makefile(s).
327 Added un-optimised support for left and left/right truncation attributes.
329 Added support for relational operators on text when using RPN queries.
331 Added support for sort specifications in RPN queries. Type 7 specifies
332 'sort' where value 1=ascending, value 2=descending. The use attribute
333 specifies the field criteria as usual. The term specifies priority
334 where 0=first, 1=second, ...
336 Changed the way use attributes are specified in the recordId
339 Maximum number of databases in one Zebra register increased.
341 New setting, databasePath, which specifies that first directory during
342 update traversal is the database name (instead of a fixed one).
344 New setting, explainDatabase, which specifies that databases are
347 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
349 Implemented EXPLAIN database maintenance. Zebra automatically
350 generate - and update CategoryList, TargetInfo, DatabaseInfo,
351 AttributeSetInfo and AttributeDetails records at this stage. The
352 records may be transferred as GRS-1, SUTRS or Explain.
354 Fixed register spec so that colon isn't treated as size separator
355 unless followed by [0-9+-] in order to allow DOS drive specifications.
357 Fixed two bugs in ISAMC system.
359 Changed the way Zebra keeps its maintenance information about attribute
360 sets, available attributes, etc.. Records in "SGML" notation using an
361 EXPLAIN schema is now used when appropriate.
363 Bug fix: Index didn't handle update/insert/delete of the same record
364 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
365 first occurence of a record is considered.
367 Most searches now return correct number of hits.
369 New modular ranking system. Interested programmers are encouraged to
370 inspect rank1.c and improve the algorithm.
372 Bug fix: Lock files weren't removed as they should on NT.
374 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
375 specify a "sort register". Refer to the gils sample records which refer
376 to index type "s" which is specified as "sort" in the default.idx file.
377 Each sort criteria can either be Ascending or Descending and at most
378 three sort elements can be specified.
380 Bug fix: Character mapping didn't work for text files.
384 Simple ranked searches now return correct number of hits.
386 The test option (-s) only makes a read-lock on the index as well
387 as using read-only operations anywhere.
389 Moved towards generic character mapping. Configuration file default.idx
390 specifies character map files for register types w, p, u, etc.
392 Implemented "begin variant" for the sgml.regx - filter.
394 Fixed a few memory leaks.
396 Added support for C++, headers uses extern "C" for public definitions.
398 Bug fix: The show records facility (-s) only displayed information for
399 the first record in a file (and not for every record in the file).
401 Added option "-f <n>" to limit the logging of record operations. After
402 <n> records has been processed no logging is performed (unless errors
405 Bug fix: the compressed ISAM system didn't handle update operations
408 Added setting, "maxResultSetSize", to hold the number of records to
409 save in a result set.
411 Bug fix: Complete phrase did't work for search operations.
413 Bug fix: temporary result sets weren't deleted.
415 Reduced disk space for saved keys (storeKeys = 1).
417 Added optional, physical ANY (key replication)
419 Implemented proximity operator in search.
421 Bug fix: the path name buffers used by file match traversal routines
422 have been extended to support long file names.
424 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
425 configuration file. The resulting register without "storeKeys" is about
426 half the size, and the memory used by zebraidx during phase 2 (merge) is
427 reduced to a minimum.
429 Reworked the way Regexp-2 queries with error tolerance are handled and
430 specified. The documentation has been updated accordingly.
432 Bug fix: Zebrasrv didn't search correctly when queries contained masking
433 characters. This bug was introduced in 1.0a8.
435 Zebrasrv now tag records with the proper database name.
437 New settings, memMax and keyTmpDir.
439 Changed name of setting lockDir (previously called lockPath) and
440 setTmpDir (previously called tempSetPath).
442 Generalized and changed record type specifications. In short, there are:
444 grs.sgml structured, "SGML-like" syntax
445 grs.regx.<filter> structured, Regular expression filter
446 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
447 is the name of an abstract syntax file.
448 Bug fix: Result sets weren't sorted in operations involving boolean
449 operations with "ranked" operands.
453 Added national character-handling subsystem.
457 Small modifications to input filters and profiles.
459 Added support for SOIF syntax (with private OID).
463 Fixed buffer-size problem in indexing.
465 Added compression to temporary files for updating.
467 Added phrase registers.
469 Added dynamic mapping of search attribute to multiple termlists (ANY).
471 Scan support in multiple databases/registers.
473 Configuration settings are case-insensitive and single dash (-)
474 characters are ignored in comparisons.
476 The index processing ignores empty files - warning given.
478 New option to zebraidx (-V) displays version information.
482 Fixed problem in file-update system.
484 Fixed problem in shadow system; register was sometimes corrupted after
489 Fixed problems in the ISAM subsystem. Caused difficulties when updating
492 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
493 the rank and record number.
495 Fixed bug in the isam subsystem - caused a malfunction when accessing
496 words which occurred more than 10000 times.
498 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
501 Server can now run under inetd. Use option -i, and -w <directory> to
502 set working directory to desired location.
504 New zebraidx command: clean - removes temporary shadow files.
506 Fixed bug in ISAM system. Occurred rarely during register updates.
508 Logging during index merge phase is improved. The remaining running
511 Temporary files generated by zebraidx are removed after each run.
513 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
514 when doing scan operations in dictionaries with European characters.
518 A whole slew of updates, to make the first publicized release. Get the doc
523 Memory-problems in ISAM fixed. More blocktypes added to the default setup
524 to increase performance on larger databases.
526 Various minor changes in data management system.
530 A couple of portability-problems resolved.
532 Changed some malloc() to xmalloc().
