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

42 Allow multiple updates within one transaction.
44 Fixed a bug with >2GB files (overflow in integer expression).
48 Fix linker error for Perl module.
50 Fix bug in and operation which in some cases could result in "extra"
51 hits. Bug was introduced in 1.3.5.
53 Fix bug in handling of schema conversion when producing numeric tags.
59 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
63 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
64 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
65 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
67 livrank: another experimental ranking algorithm. Source in livcode.c.
68 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
70 Contributed by Pete Mallinson, University of Liverpool.
72 Advanced MARC indexing. See doc/marc_indexing.xml
73 Oleg Kolobov <oleg at lib.tpu.ru>
75 Perl API updates and fixes.
76 Peter Popovics <pop at technomat.hu>
78 Fixed 'zebraidx delete'.
80 Implemented 'zebraidx clean'.
82 64-bit offsets for register files on WIN32 (no 2 GB limit).
84 Fixed a few memory leaks WRT sorting.
88 Fixed error handling : error code was not properly returned.
90 Support Truncation 104 (CCL).
94 Added missing source files for perl extension.
98 Implemented xelm directive.
100 Updated for newer version of YAZ (introduction of string schema).
102 Directory examples/zthes now part of distribution (was missing
103 in previous release).
105 New .abs directive, systag, that control where to put retrieval
106 information. The directive takes two arguments: system tag, element name.
107 System tag is one of : rank, sysno, size.
111 Perl Filter and Perl API. By Peter Popovics.
113 For zebra.cfg, if no profilePath is specified, directory
114 (prefix)/share/idzebra/tab
117 Zebra Examples in examples . Zebra tests in test.
119 Bug fix: sort index was not properly modified on
120 record updates/deletes.
122 Fix handling of character entities for sgml filter.
124 Move data1 to Zebra (used to be part of YAZ).
128 Fix character encoding of scan response terms.
130 Fix character decoding of scan request terms.
132 Fix ESpec handling (requires YAZ 1.9.1)
134 Fix searches for complete fields.
138 When name zebra is used in a filename or directory 'idzebra' is used
139 instead to avoid confusion with GNU zebra (routing software).
141 Zebra server stops with a fatal error if config file cannot be read.
143 New config setting, followLinks, that controls whether update of files
144 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
145 By default symbolic links are followed.
147 Fix MARC transfer . MARC fields had wrong data for multiple fields.
149 XML record reader moved from YAZ to Zebra, to make YAZ less
150 dependant on external libraries.
152 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
153 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
154 on systems that doesn't offer iconv.
156 XML record reader supports external system entities.
160 New .abs-directive "xpath" that takes one argument: "enable"
161 or "disable" to enable and disable XPath -indexing. If no "xpath"
162 direcive is found in .abs-file , XPath-indexing is disabled to ensure
163 backwards compatibility. For missing .abs-files XPath-indexing is
164 enabled so that such records are searchable.
166 Zebra warns about missing .abs-file only once (for each type).
168 Fixed a bug in file update where already-inserted files could
173 Zebra license changed to GNU GPL.
175 XPath-like queries used when RPN string attributes are used, eg.
176 @attr 1=/portal/title sometitle
177 @attr 1=/portal/title[@xml:lang=da] danishtitle
178 @attr 1=/portal/title/@xml:lang da
179 @attr 1=//title sometitle
181 Zebra uses UTF-8 internally:
182 1) New setting "encoding" for zebra.cfg that specifies encoding for
183 OCTET terms in queries and record encoding for most transfer syntaxes
184 (except those that use International Strings, such as GRS-1).
185 2) The encoding of International strings is UTF-8 by default. It
186 may be changed by character set negotiation. If character set
187 negotiation is in effect and if records are selected for conversion
188 these'll be converted to the selected character set - thus overriding
189 the encoding setting in zebra.cfg.
190 3) New directive "encoding" in .abs-files. This specifies the external
191 character encoding for files indexed by zebra. However, if records
192 themselves have an XML header that specifies and encoding that'll be used
195 XML filter (-t grs.xml).
197 Multiple registers. New setting in resource 'root' that holds base
198 directory for register(s). A group a databases may be put in separate
199 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
203 Fixes for Digital Unix
205 Implemented hits per term using USR:SearchResult-1.
207 New Zebra API. Locking system re-implemented.
209 --- 1.1.stable 2002/02/20
211 Rank weight can be controlled with attribute type 9. Default
212 value is 34. Recommended values between 1-36.
216 Updated for YAZ version 1.8.
218 Added support for termsets - a result set of terms matching
219 a given query. For @attr 8=<set> creates termset named <set>.
221 Added support for raw retrieval. Element Set Name R forces the
222 text filter which returns the record in its original form.
224 Added numerical sort - triggered by structure=numeric (4=109).
226 Remote record import using Z39.50 Extended Services and Segments.
228 Fixed bug where updating a database with user-defined attributes
229 could corrupt the register (bad storeKeys).
231 Multi-threaded version.
233 Fixed bug regarding proximity.
235 Documentation updates.
237 Fixed bug in record retrieval module that occured on 64-bit OSF
242 Fixed bug in makefile for WIN32.
244 Fixed bug in configure script - used bash-specific features.
248 Added support for multiple records in one file for filter grs.sgml.
250 Changed record index structure. New layout is incompatible with
251 previous releases. Added setting "recordcompression" to control
252 compression of records. Possible values are "none" (no
253 compression) and bzip2 (compression using libbz2).
255 Added XML transfer syntax support for retrieval of structured records.
256 Schema in CompSpec is recognised in retrieval of structured records.
258 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
259 that fails, the filter reads the file <filt>.flt (regx style filter).
261 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
262 Zebra's configure script automatically attempts to locate Tcl. For
263 manual Tcl configuration use option --with-tclconfig=<path> to specify
264 where Tcl's library files are located.
266 Implemented "compression" of Dictionary and ISAM system. Dictionary
269 Added "tagsysno" directive to zebra.cfg to control under which tag the
270 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
273 Added "tagrank" as above.
275 Changed file naming scheme for register files from <name>.mf.<no> to
278 Implemented "position"-flag for register type (as defined in
279 default.idx). When set to zero no position (or seqence number) is
280 saved in register for each word occurrence, thus saving some register
283 Implemented database mapping. Using mapdb one can specify a database
284 to be mapped to one or more physical databases. Usage:
285 mapdb <fromdb> <todb> ..
287 Added SOIF-filter. Thanks to Peter Valkenburg.
289 For the regx-filter "end element -record" may trigger a mark-of-record
290 if outer level is reached.
292 Tag sets may be typed in the reference to it. From the .abs-file the
293 "tagset" directive takes a third optional integer type for the tag set
294 referenced. From a .tag-file the "include" directive takes a third
295 optional type as well. The old "type" directive in the tag set itself
296 is still recognized but acts as the default type for the tag set.
298 Zebra supports the specification of arbitrary attributes sets, schemas
299 and tag sets, because of the change in YAZ' OID management system.
301 Fixed bug in Sort that caused it NOT to use character mapping as it
304 Zebra now uses GNU configure to generate Makefile(s).
306 Added un-optimised support for left and left/right truncation attributes.
308 Added support for relational operators on text when using RPN queries.
310 Added support for sort specifications in RPN queries. Type 7 specifies
311 'sort' where value 1=ascending, value 2=descending. The use attribute
312 specifies the field criteria as usual. The term specifies priority
313 where 0=first, 1=second, ...
315 Changed the way use attributes are specified in the recordId
318 Maximum number of databases in one Zebra register increased.
320 New setting, databasePath, which specifies that first directory during
321 update traversal is the database name (instead of a fixed one).
323 New setting, explainDatabase, which specifies that databases are
326 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
328 Implemented EXPLAIN database maintenance. Zebra automatically
329 generate - and update CategoryList, TargetInfo, DatabaseInfo,
330 AttributeSetInfo and AttributeDetails records at this stage. The
331 records may be transferred as GRS-1, SUTRS or Explain.
333 Fixed register spec so that colon isn't treated as size separator
334 unless followed by [0-9+-] in order to allow DOS drive specifications.
336 Fixed two bugs in ISAMC system.
338 Changed the way Zebra keeps its maintenance information about attribute
339 sets, available attributes, etc.. Records in "SGML" notation using an
340 EXPLAIN schema is now used when appropriate.
342 Bug fix: Index didn't handle update/insert/delete of the same record
343 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
344 first occurence of a record is considered.
346 Most searches now return correct number of hits.
348 New modular ranking system. Interested programmers are encouraged to
349 inspect rank1.c and improve the algorithm.
351 Bug fix: Lock files weren't removed as they should on NT.
353 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
354 specify a "sort register". Refer to the gils sample records which refer
355 to index type "s" which is specified as "sort" in the default.idx file.
356 Each sort criteria can either be Ascending or Descending and at most
357 three sort elements can be specified.
359 Bug fix: Character mapping didn't work for text files.
363 Simple ranked searches now return correct number of hits.
365 The test option (-s) only makes a read-lock on the index as well
366 as using read-only operations anywhere.
368 Moved towards generic character mapping. Configuration file default.idx
369 specifies character map files for register types w, p, u, etc.
371 Implemented "begin variant" for the sgml.regx - filter.
373 Fixed a few memory leaks.
375 Added support for C++, headers uses extern "C" for public definitions.
377 Bug fix: The show records facility (-s) only displayed information for
378 the first record in a file (and not for every record in the file).
380 Added option "-f <n>" to limit the logging of record operations. After
381 <n> records has been processed no logging is performed (unless errors
384 Bug fix: the compressed ISAM system didn't handle update operations
387 Added setting, "maxResultSetSize", to hold the number of records to
388 save in a result set.
390 Bug fix: Complete phrase did't work for search operations.
392 Bug fix: temporary result sets weren't deleted.
394 Reduced disk space for saved keys (storeKeys = 1).
396 Added optional, physical ANY (key replication)
398 Implemented proximity operator in search.
400 Bug fix: the path name buffers used by file match traversal routines
401 have been extended to support long file names.
403 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
404 configuration file. The resulting register without "storeKeys" is about
405 half the size, and the memory used by zebraidx during phase 2 (merge) is
406 reduced to a minimum.
408 Reworked the way Regexp-2 queries with error tolerance are handled and
409 specified. The documentation has been updated accordingly.
411 Bug fix: Zebrasrv didn't search correctly when queries contained masking
412 characters. This bug was introduced in 1.0a8.
414 Zebrasrv now tag records with the proper database name.
416 New settings, memMax and keyTmpDir.
418 Changed name of setting lockDir (previously called lockPath) and
419 setTmpDir (previously called tempSetPath).
421 Generalized and changed record type specifications. In short, there are:
423 grs.sgml structured, "SGML-like" syntax
424 grs.regx.<filter> structured, Regular expression filter
425 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
426 is the name of an abstract syntax file.
427 Bug fix: Result sets weren't sorted in operations involving boolean
428 operations with "ranked" operands.
432 Added national character-handling subsystem.
436 Small modifications to input filters and profiles.
438 Added support for SOIF syntax (with private OID).
442 Fixed buffer-size problem in indexing.
444 Added compression to temporary files for updating.
446 Added phrase registers.
448 Added dynamic mapping of search attribute to multiple termlists (ANY).
450 Scan support in multiple databases/registers.
452 Configuration settings are case-insensitive and single dash (-)
453 characters are ignored in comparisons.
455 The index processing ignores empty files - warning given.
457 New option to zebraidx (-V) displays version information.
461 Fixed problem in file-update system.
463 Fixed problem in shadow system; register was sometimes corrupted after
468 Fixed problems in the ISAM subsystem. Caused difficulties when updating
471 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
472 the rank and record number.
474 Fixed bug in the isam subsystem - caused a malfunction when accessing
475 words which occurred more than 10000 times.
477 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
480 Server can now run under inetd. Use option -i, and -w <directory> to
481 set working directory to desired location.
483 New zebraidx command: clean - removes temporary shadow files.
485 Fixed bug in ISAM system. Occurred rarely during register updates.
487 Logging during index merge phase is improved. The remaining running
490 Temporary files generated by zebraidx are removed after each run.
492 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
493 when doing scan operations in dictionaries with European characters.
497 A whole slew of updates, to make the first publicized release. Get the doc
502 Memory-problems in ISAM fixed. More blocktypes added to the default setup
503 to increase performance on larger databases.
505 Various minor changes in data management system.
509 A couple of portability-problems resolved.
511 Changed some malloc() to xmalloc().
