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

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

75 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
77 livrank: another experimental ranking algorithm. Source in livcode.c.
78 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
80 Contributed by Pete Mallinson, University of Liverpool.
82 Advanced MARC indexing. See doc/marc_indexing.xml
83 Oleg Kolobov <oleg at lib.tpu.ru>
85 Perl API updates and fixes.
86 Peter Popovics <pop at technomat.hu>
88 Fixed 'zebraidx delete'.
90 Implemented 'zebraidx clean'.
92 64-bit offsets for register files on WIN32 (no 2 GB limit).
94 Fixed a few memory leaks WRT sorting.
98 Fixed error handling : error code was not properly returned.
100 Support Truncation 104 (CCL).
104 Added missing source files for perl extension.
108 Implemented xelm directive.
110 Updated for newer version of YAZ (introduction of string schema).
112 Directory examples/zthes now part of distribution (was missing
113 in previous release).
115 New .abs directive, systag, that control where to put retrieval
116 information. The directive takes two arguments: system tag, element name.
117 System tag is one of : rank, sysno, size.
121 Perl Filter and Perl API. By Peter Popovics.
123 For zebra.cfg, if no profilePath is specified, directory
124 (prefix)/share/idzebra/tab
127 Zebra Examples in examples . Zebra tests in test.
129 Bug fix: sort index was not properly modified on
130 record updates/deletes.
132 Fix handling of character entities for sgml filter.
134 Move data1 to Zebra (used to be part of YAZ).
138 Fix character encoding of scan response terms.
140 Fix character decoding of scan request terms.
142 Fix ESpec handling (requires YAZ 1.9.1)
144 Fix searches for complete fields.
148 When name zebra is used in a filename or directory 'idzebra' is used
149 instead to avoid confusion with GNU zebra (routing software).
151 Zebra server stops with a fatal error if config file cannot be read.
153 New config setting, followLinks, that controls whether update of files
154 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
155 By default symbolic links are followed.
157 Fix MARC transfer . MARC fields had wrong data for multiple fields.
159 XML record reader moved from YAZ to Zebra, to make YAZ less
160 dependant on external libraries.
162 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
163 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
164 on systems that doesn't offer iconv.
166 XML record reader supports external system entities.
170 New .abs-directive "xpath" that takes one argument: "enable"
171 or "disable" to enable and disable XPath -indexing. If no "xpath"
172 direcive is found in .abs-file , XPath-indexing is disabled to ensure
173 backwards compatibility. For missing .abs-files XPath-indexing is
174 enabled so that such records are searchable.
176 Zebra warns about missing .abs-file only once (for each type).
178 Fixed a bug in file update where already-inserted files could
183 Zebra license changed to GNU GPL.
185 XPath-like queries used when RPN string attributes are used, eg.
186 @attr 1=/portal/title sometitle
187 @attr 1=/portal/title[@xml:lang=da] danishtitle
188 @attr 1=/portal/title/@xml:lang da
189 @attr 1=//title sometitle
191 Zebra uses UTF-8 internally:
192 1) New setting "encoding" for zebra.cfg that specifies encoding for
193 OCTET terms in queries and record encoding for most transfer syntaxes
194 (except those that use International Strings, such as GRS-1).
195 2) The encoding of International strings is UTF-8 by default. It
196 may be changed by character set negotiation. If character set
197 negotiation is in effect and if records are selected for conversion
198 these'll be converted to the selected character set - thus overriding
199 the encoding setting in zebra.cfg.
200 3) New directive "encoding" in .abs-files. This specifies the external
201 character encoding for files indexed by zebra. However, if records
202 themselves have an XML header that specifies and encoding that'll be used
205 XML filter (-t grs.xml).
207 Multiple registers. New setting in resource 'root' that holds base
208 directory for register(s). A group a databases may be put in separate
209 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
213 Fixes for Digital Unix
215 Implemented hits per term using USR:SearchResult-1.
217 New Zebra API. Locking system re-implemented.
219 --- 1.1.stable 2002/02/20
221 Rank weight can be controlled with attribute type 9. Default
222 value is 34. Recommended values between 1-36.
226 Updated for YAZ version 1.8.
228 Added support for termsets - a result set of terms matching
229 a given query. For @attr 8=<set> creates termset named <set>.
231 Added support for raw retrieval. Element Set Name R forces the
232 text filter which returns the record in its original form.
234 Added numerical sort - triggered by structure=numeric (4=109).
236 Remote record import using Z39.50 Extended Services and Segments.
238 Fixed bug where updating a database with user-defined attributes
239 could corrupt the register (bad storeKeys).
241 Multi-threaded version.
243 Fixed bug regarding proximity.
245 Documentation updates.
247 Fixed bug in record retrieval module that occured on 64-bit OSF
252 Fixed bug in makefile for WIN32.
254 Fixed bug in configure script - used bash-specific features.
258 Added support for multiple records in one file for filter grs.sgml.
260 Changed record index structure. New layout is incompatible with
261 previous releases. Added setting "recordcompression" to control
262 compression of records. Possible values are "none" (no
263 compression) and bzip2 (compression using libbz2).
265 Added XML transfer syntax support for retrieval of structured records.
266 Schema in CompSpec is recognised in retrieval of structured records.
268 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
269 that fails, the filter reads the file <filt>.flt (regx style filter).
271 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
272 Zebra's configure script automatically attempts to locate Tcl. For
273 manual Tcl configuration use option --with-tclconfig=<path> to specify
274 where Tcl's library files are located.
276 Implemented "compression" of Dictionary and ISAM system. Dictionary
279 Added "tagsysno" directive to zebra.cfg to control under which tag the
280 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
283 Added "tagrank" as above.
285 Changed file naming scheme for register files from <name>.mf.<no> to
288 Implemented "position"-flag for register type (as defined in
289 default.idx). When set to zero no position (or seqence number) is
290 saved in register for each word occurrence, thus saving some register
293 Implemented database mapping. Using mapdb one can specify a database
294 to be mapped to one or more physical databases. Usage:
295 mapdb <fromdb> <todb> ..
297 Added SOIF-filter. Thanks to Peter Valkenburg.
299 For the regx-filter "end element -record" may trigger a mark-of-record
300 if outer level is reached.
302 Tag sets may be typed in the reference to it. From the .abs-file the
303 "tagset" directive takes a third optional integer type for the tag set
304 referenced. From a .tag-file the "include" directive takes a third
305 optional type as well. The old "type" directive in the tag set itself
306 is still recognized but acts as the default type for the tag set.
308 Zebra supports the specification of arbitrary attributes sets, schemas
309 and tag sets, because of the change in YAZ' OID management system.
311 Fixed bug in Sort that caused it NOT to use character mapping as it
314 Zebra now uses GNU configure to generate Makefile(s).
316 Added un-optimised support for left and left/right truncation attributes.
318 Added support for relational operators on text when using RPN queries.
320 Added support for sort specifications in RPN queries. Type 7 specifies
321 'sort' where value 1=ascending, value 2=descending. The use attribute
322 specifies the field criteria as usual. The term specifies priority
323 where 0=first, 1=second, ...
325 Changed the way use attributes are specified in the recordId
328 Maximum number of databases in one Zebra register increased.
330 New setting, databasePath, which specifies that first directory during
331 update traversal is the database name (instead of a fixed one).
333 New setting, explainDatabase, which specifies that databases are
336 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
338 Implemented EXPLAIN database maintenance. Zebra automatically
339 generate - and update CategoryList, TargetInfo, DatabaseInfo,
340 AttributeSetInfo and AttributeDetails records at this stage. The
341 records may be transferred as GRS-1, SUTRS or Explain.
343 Fixed register spec so that colon isn't treated as size separator
344 unless followed by [0-9+-] in order to allow DOS drive specifications.
346 Fixed two bugs in ISAMC system.
348 Changed the way Zebra keeps its maintenance information about attribute
349 sets, available attributes, etc.. Records in "SGML" notation using an
350 EXPLAIN schema is now used when appropriate.
352 Bug fix: Index didn't handle update/insert/delete of the same record
353 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
354 first occurence of a record is considered.
356 Most searches now return correct number of hits.
358 New modular ranking system. Interested programmers are encouraged to
359 inspect rank1.c and improve the algorithm.
361 Bug fix: Lock files weren't removed as they should on NT.
363 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
364 specify a "sort register". Refer to the gils sample records which refer
365 to index type "s" which is specified as "sort" in the default.idx file.
366 Each sort criteria can either be Ascending or Descending and at most
367 three sort elements can be specified.
369 Bug fix: Character mapping didn't work for text files.
373 Simple ranked searches now return correct number of hits.
375 The test option (-s) only makes a read-lock on the index as well
376 as using read-only operations anywhere.
378 Moved towards generic character mapping. Configuration file default.idx
379 specifies character map files for register types w, p, u, etc.
381 Implemented "begin variant" for the sgml.regx - filter.
383 Fixed a few memory leaks.
385 Added support for C++, headers uses extern "C" for public definitions.
387 Bug fix: The show records facility (-s) only displayed information for
388 the first record in a file (and not for every record in the file).
390 Added option "-f <n>" to limit the logging of record operations. After
391 <n> records has been processed no logging is performed (unless errors
394 Bug fix: the compressed ISAM system didn't handle update operations
397 Added setting, "maxResultSetSize", to hold the number of records to
398 save in a result set.
400 Bug fix: Complete phrase did't work for search operations.
402 Bug fix: temporary result sets weren't deleted.
404 Reduced disk space for saved keys (storeKeys = 1).
406 Added optional, physical ANY (key replication)
408 Implemented proximity operator in search.
410 Bug fix: the path name buffers used by file match traversal routines
411 have been extended to support long file names.
413 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
414 configuration file. The resulting register without "storeKeys" is about
415 half the size, and the memory used by zebraidx during phase 2 (merge) is
416 reduced to a minimum.
418 Reworked the way Regexp-2 queries with error tolerance are handled and
419 specified. The documentation has been updated accordingly.
421 Bug fix: Zebrasrv didn't search correctly when queries contained masking
422 characters. This bug was introduced in 1.0a8.
424 Zebrasrv now tag records with the proper database name.
426 New settings, memMax and keyTmpDir.
428 Changed name of setting lockDir (previously called lockPath) and
429 setTmpDir (previously called tempSetPath).
431 Generalized and changed record type specifications. In short, there are:
433 grs.sgml structured, "SGML-like" syntax
434 grs.regx.<filter> structured, Regular expression filter
435 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
436 is the name of an abstract syntax file.
437 Bug fix: Result sets weren't sorted in operations involving boolean
438 operations with "ranked" operands.
442 Added national character-handling subsystem.
446 Small modifications to input filters and profiles.
448 Added support for SOIF syntax (with private OID).
452 Fixed buffer-size problem in indexing.
454 Added compression to temporary files for updating.
456 Added phrase registers.
458 Added dynamic mapping of search attribute to multiple termlists (ANY).
460 Scan support in multiple databases/registers.
462 Configuration settings are case-insensitive and single dash (-)
463 characters are ignored in comparisons.
465 The index processing ignores empty files - warning given.
467 New option to zebraidx (-V) displays version information.
471 Fixed problem in file-update system.
473 Fixed problem in shadow system; register was sometimes corrupted after
478 Fixed problems in the ISAM subsystem. Caused difficulties when updating
481 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
482 the rank and record number.
484 Fixed bug in the isam subsystem - caused a malfunction when accessing
485 words which occurred more than 10000 times.
487 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
490 Server can now run under inetd. Use option -i, and -w <directory> to
491 set working directory to desired location.
493 New zebraidx command: clean - removes temporary shadow files.
495 Fixed bug in ISAM system. Occurred rarely during register updates.
497 Logging during index merge phase is improved. The remaining running
500 Temporary files generated by zebraidx are removed after each run.
502 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
503 when doing scan operations in dictionaries with European characters.
507 A whole slew of updates, to make the first publicized release. Get the doc
512 Memory-problems in ISAM fixed. More blocktypes added to the default setup
513 to increase performance on larger databases.
515 Various minor changes in data management system.
519 A couple of portability-problems resolved.
521 Changed some malloc() to xmalloc().
