3 (prefix)/share/idzebra/tab
6 Zebra Examples in examples . Zebra tests in test.
8 Bug fix: sort index was not properly modified on
9 record updates/deletes.
11 Move data1 to Zebra (used to be part of YAZ).
15 Fix character encoding of scan response terms.
17 Fix character decoding of scan request terms.
19 Fix ESpec handling (requires YAZ 1.9.1)
21 Fix searches for complete fields.
25 When name zebra is used in a filename or directory 'idzebra' is used
26 instead to avoid confusion with GNU zebra (routing software).
28 Zebra server stops with a fatal error if config file cannot be read.
30 New config setting, followLinks, that controls whether update of files
31 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
32 By default symbolic links are followed.
34 Fix MARC transfer . MARC fields had wrong data for multiple fields.
36 XML record reader moved from YAZ to Zebra, to make YAZ less
37 dependant on external libraries.
39 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
40 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
41 on systems that doesn't offer iconv.
43 XML record reader supports external system entities.
47 New .abs-directive "xpath" that takes one argument: "enable"
48 or "disable" to enable and disable XPath -indexing. If no "xpath"
49 direcive is found in .abs-file , XPath-indexing is disabled to ensure
50 backwards compatibility. For missing .abs-files XPath-indexing is
51 enabled so that such records are searchable.
53 Zebra warns about missing .abs-file only once (for each type).
55 Fixed a bug in file update where already-inserted files could
60 Zebra license changed to GNU GPL.
62 XPath-like queries used when RPN string attributes are used, eg.
63 @attr 1=/portal/title sometitle
64 @attr 1=/portal/title[@xml:lang=da] danishtitle
65 @attr 1=/portal/title/@xml:lang da
66 @attr 1=//title sometitle
68 Zebra uses UTF-8 internally:
69 1) New setting "encoding" for zebra.cfg that specifies encoding for
70 OCTET terms in queries and record encoding for most transfer syntaxes
71 (except those that use International Strings, such as GRS-1).
72 2) The encoding of International strings is UTF-8 by default. It
73 may be changed by character set negotiation. If character set
74 negotiation is in effect and if records are selected for conversion
75 these'll be converted to the selected character set - thus overriding
76 the encoding setting in zebra.cfg.
77 3) New directive "encoding" in .abs-files. This specifies the external
78 character encoding for files indexed by zebra. However, if records
79 themselves have an XML header that specifies and encoding that'll be used
82 XML filter (-t grs.xml).
84 Multiple registers. New setting in resource 'root' that holds base
85 directory for register(s). A group a databases may be put in separate
86 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
90 Fixes for Digital Unix
92 Implemented hits per term using USR:SearchResult-1.
94 New Zebra API. Locking system re-implemented.
96 --- 1.1.stable 2002/02/20
98 Rank weight can be controlled with attribute type 9. Default
99 value is 34. Recommended values between 1-36.
103 Updated for YAZ version 1.8.
105 Added support for termsets - a result set of terms matching
106 a given query. For @attr 8=<set> creates termset named <set>.
108 Added support for raw retrieval. Element Set Name R forces the
109 text filter which returns the record in its original form.
111 Added numerical sort - triggered by structure=numeric (4=109).
113 Remote record import using Z39.50 Extended Services and Segments.
115 Fixed bug where updating a database with user-defined attributes
116 could corrupt the register (bad storeKeys).
118 Multi-threaded version.
120 Fixed bug regarding proximity.
122 Documentation updates.
124 Fixed bug in record retrieval module that occured on 64-bit OSF
129 Fixed bug in makefile for WIN32.
131 Fixed bug in configure script - used bash-specific features.
135 Added support for multiple records in one file for filter grs.sgml.
137 Changed record index structure. New layout is incompatible with
138 previous releases. Added setting "recordcompression" to control
139 compression of records. Possible values are "none" (no
140 compression) and bzip2 (compression using libbz2).
142 Added XML transfer syntax support for retrieval of structured records.
143 Schema in CompSpec is recognised in retrieval of structured records.
145 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
146 that fails, the filter reads the file <filt>.flt (regx style filter).
148 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
149 Zebra's configure script automatically attempts to locate Tcl. For
150 manual Tcl configuration use option --with-tclconfig=<path> to specify
151 where Tcl's library files are located.
153 Implemented "compression" of Dictionary and ISAM system. Dictionary
156 Added "tagsysno" directive to zebra.cfg to control under which tag the
157 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
160 Added "tagrank" as above.
162 Changed file naming scheme for register files from <name>.mf.<no> to
165 Implemented "position"-flag for register type (as defined in
166 default.idx). When set to zero no position (or seqence number) is
167 saved in register for each word occurrence, thus saving some register
170 Implemented database mapping. Using mapdb one can specify a database
171 to be mapped to one or more physical databases. Usage:
172 mapdb <fromdb> <todb> ..
174 Added SOIF-filter. Thanks to Peter Valkenburg.
176 For the regx-filter "end element -record" may trigger a mark-of-record
177 if outer level is reached.
179 Tag sets may be typed in the reference to it. From the .abs-file the
180 "tagset" directive takes a third optional integer type for the tag set
181 referenced. From a .tag-file the "include" directive takes a third
182 optional type as well. The old "type" directive in the tag set itself
183 is still recognized but acts as the default type for the tag set.
185 Zebra supports the specification of arbitrary attributes sets, schemas
186 and tag sets, because of the change in YAZ' OID management system.
188 Fixed bug in Sort that caused it NOT to use character mapping as it
191 Zebra now uses GNU configure to generate Makefile(s).
193 Added un-optimised support for left and left/right truncation attributes.
195 Added support for relational operators on text when using RPN queries.
197 Added support for sort specifications in RPN queries. Type 7 specifies
198 'sort' where value 1=ascending, value 2=descending. The use attribute
199 specifies the field criteria as usual. The term specifies priority
200 where 0=first, 1=second, ...
202 Changed the way use attributes are specified in the recordId
205 Maximum number of databases in one Zebra register increased.
207 New setting, databasePath, which specifies that first directory during
208 update traversal is the database name (instead of a fixed one).
210 New setting, explainDatabase, which specifies that databases are
213 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
215 Implemented EXPLAIN database maintenance. Zebra automatically
216 generate - and update CategoryList, TargetInfo, DatabaseInfo,
217 AttributeSetInfo and AttributeDetails records at this stage. The
218 records may be transferred as GRS-1, SUTRS or Explain.
220 Fixed register spec so that colon isn't treated as size separator
221 unless followed by [0-9+-] in order to allow DOS drive specifications.
223 Fixed two bugs in ISAMC system.
225 Changed the way Zebra keeps its maintenance information about attribute
226 sets, available attributes, etc.. Records in "SGML" notation using an
227 EXPLAIN schema is now used when appropriate.
229 Bug fix: Index didn't handle update/insert/delete of the same record
230 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
231 first occurence of a record is considered.
233 Most searches now return correct number of hits.
235 New modular ranking system. Interested programmers are encouraged to
236 inspect rank1.c and improve the algorithm.
238 Bug fix: Lock files weren't removed as they should on NT.
240 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
241 specify a "sort register". Refer to the gils sample records which refer
242 to index type "s" which is specified as "sort" in the default.idx file.
243 Each sort criteria can either be Ascending or Descending and at most
244 three sort elements can be specified.
246 Bug fix: Character mapping didn't work for text files.
250 Simple ranked searches now return correct number of hits.
252 The test option (-s) only makes a read-lock on the index as well
253 as using read-only operations anywhere.
255 Moved towards generic character mapping. Configuration file default.idx
256 specifies character map files for register types w, p, u, etc.
258 Implemented "begin variant" for the sgml.regx - filter.
260 Fixed a few memory leaks.
262 Added support for C++, headers uses extern "C" for public definitions.
264 Bug fix: The show records facility (-s) only displayed information for
265 the first record in a file (and not for every record in the file).
267 Added option "-f <n>" to limit the logging of record operations. After
268 <n> records has been processed no logging is performed (unless errors
271 Bug fix: the compressed ISAM system didn't handle update operations
274 Added setting, "maxResultSetSize", to hold the number of records to
275 save in a result set.
277 Bug fix: Complete phrase did't work for search operations.
279 Bug fix: temporary result sets weren't deleted.
281 Reduced disk space for saved keys (storeKeys = 1).
283 Added optional, physical ANY (key replication)
285 Implemented proximity operator in search.
287 Bug fix: the path name buffers used by file match traversal routines
288 have been extended to support long file names.
290 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
291 configuration file. The resulting register without "storeKeys" is about
292 half the size, and the memory used by zebraidx during phase 2 (merge) is
293 reduced to a minimum.
295 Reworked the way Regexp-2 queries with error tolerance are handled and
296 specified. The documentation has been updated accordingly.
298 Bug fix: Zebrasrv didn't search correctly when queries contained masking
299 characters. This bug was introduced in 1.0a8.
301 Zebrasrv now tag records with the proper database name.
303 New settings, memMax and keyTmpDir.
305 Changed name of setting lockDir (previously called lockPath) and
306 setTmpDir (previously called tempSetPath).
308 Generalized and changed record type specifications. In short, there are:
310 grs.sgml structured, "SGML-like" syntax
311 grs.regx.<filter> structured, Regular expression filter
312 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
313 is the name of an abstract syntax file.
314 Bug fix: Result sets weren't sorted in operations involving boolean
315 operations with "ranked" operands.
319 Added national character-handling subsystem.
323 Small modifications to input filters and profiles.
325 Added support for SOIF syntax (with private OID).
329 Fixed buffer-size problem in indexing.
331 Added compression to temporary files for updating.
333 Added phrase registers.
335 Added dynamic mapping of search attribute to multiple termlists (ANY).
337 Scan support in multiple databases/registers.
339 Configuration settings are case-insensitive and single dash (-)
340 characters are ignored in comparisons.
342 The index processing ignores empty files - warning given.
344 New option to zebraidx (-V) displays version information.
348 Fixed problem in file-update system.
350 Fixed problem in shadow system; register was sometimes corrupted after
355 Fixed problems in the ISAM subsystem. Caused difficulties when updating
358 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
359 the rank and record number.
361 Fixed bug in the isam subsystem - caused a malfunction when accessing
362 words which occurred more than 10000 times.
364 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
367 Server can now run under inetd. Use option -i, and -w <directory> to
368 set working directory to desired location.
370 New zebraidx command: clean - removes temporary shadow files.
372 Fixed bug in ISAM system. Occurred rarely during register updates.
374 Logging during index merge phase is improved. The remaining running
377 Temporary files generated by zebraidx are removed after each run.
379 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
380 when doing scan operations in dictionaries with European characters.
384 A whole slew of updates, to make the first publicized release. Get the doc
389 Memory-problems in ISAM fixed. More blocktypes added to the default setup
390 to increase performance on larger databases.
392 Various minor changes in data management system.
396 A couple of portability-problems resolved.
398 Changed some malloc() to xmalloc().
