1 Fixed bug in Sort that caused it NOT to use character mapping as
4 Zebra now uses GNU configure to generate Makefile(s).
6 Added un-optimised support for left and left/right truncation attributes.
8 Added support for relational operators on text when using
11 Added support for sort specifications in RPN queries. Type 7
12 specifies 'sort' where value 1=ascending, value 2=descending.
13 The use attribute specifies the field criteria as usual.
14 The term specifies priority (0=first, 1=second).
16 Changed the way use attributes are specified in the recordId
19 Maximum number of databases in one Zebra register increased.
21 New setting, databasePath, which specifies that first directory
22 during update traversal is the database name (instead of
25 New setting, explainDatabase, which specifies that databases
28 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
30 Implemented EXPLAIN database maintenance. Zebra automatically
31 generate - and update CategoryList, TargetInfo, DatabaseInfo,
32 AttributeSetInfo and AttributeDetails records at this stage.
33 The records may be transferred as GRS-1, SUTRS or Explain.
35 Fixed register spec so that colon isn't treated as size separator
36 unless followed by [0-9+-] in order to allow DOS drive specifications.
38 Fixed two bugs in ISAMC system.
40 Changed the way Zebra keeps its maintenance information. Records
41 in "SGML" notation using an EXPLAIN schema is now used when
44 Bug fix: Index didn't handle update/insert/delete of the same
45 record (i.e. same recordId) in one run (one invocation of zebraidx).
46 Only the first occurence of a record is considered.
48 Most searches now return correct number of hits.
50 New modular ranking system. Interested programmers are encouraged to
51 inspect rank1.c and improve the algorithm.
53 Bug fix: Lock files weren't removed as they should when using NT.
55 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
56 specify a "sort register". Refer to the gils sample records which
57 refer to index type "s" which is specified as "sort" in the default.idx
58 file. Each sort criteria can either be Ascending or Descending and
59 at most three sort elements can be specified.
61 Bug fix: Character mapping didn't work for text files.
65 Simple ranked searches now return correct number of hits.
67 The test option (-s) only makes a read-lock on the index as well
68 as using read-only operations anywhere.
70 Moved towards generic character mapping. Configuration file default.idx
71 specifies character map files for register types w, p, u, etc.
73 Implemented "begin variant" for the sgml.regx - filter.
75 Fixed a few memory leaks.
77 Added support for C++, headers uses extern "C" for public definitions.
79 Bug fix: The show records facility (-s) only displayed information for
80 the first record in a file (and not for every record in the file).
82 Added option "-f <n>" to limit the logging of record operations. After
83 <n> records has been processed no logging is performed (unless errors
86 Bug fix: the compressed ISAM system didn't handle update operations
89 Added setting, "maxResultSetSize", to hold the number of records to
92 Bug fix: Complete phrase did't work for search operations.
94 Bug fix: temporary result sets weren't deleted.
96 Reduced disk space for saved keys (storeKeys = 1).
98 Added optional, physical ANY (key replication)
100 Implemented proximity operator in search.
102 Bug fix: the path name buffers used by file match traversal routines
103 have been extended to support long file names.
105 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
106 configuration file. The resulting register without "storeKeys" is about
107 half the size, and the memory used by zebraidx during phase 2 (merge) is
108 reduced to a minimum.
110 Reworked the way Regexp-2 queries with error tolerance are handled and
111 specified. The documentation has been updated accordingly.
113 Bug fix: Zebrasrv didn't search correctly when queries contained masking
114 characters. This bug was introduced in 1.0a8.
116 Zebrasrv now tag records with the proper database name.
118 New settings, memMax and keyTmpDir.
120 Changed name of setting lockDir (previously called lockPath) and
121 setTmpDir (previously called tempSetPath).
123 Generalized and changed record type specifications. In short, there are:
125 grs.sgml structured, "SGML-like" syntax
126 grs.regx.<filter> structured, Regular expression filter
127 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
128 is the name of an abstract syntax file.
129 Bug fix: Result sets weren't sorted in operations involving boolean
130 operations with "ranked" operands.
134 Added national character-handling subsystem.
138 Small modifications to input filters and profiles.
140 Added support for SOIF syntax (with private OID).
144 Fixed buffer-size problem in indexing.
146 Added compression to temporary files for updating.
148 Added phrase registers.
150 Added dynamic mapping of search attribute to multiple termlists (ANY).
152 Scan support in multiple databases/registers.
154 Configuration settings are case-insensitive and single dash (-)
155 characters are ignored in comparisons.
157 The index processing ignores empty files - warning given.
159 New option to zebraidx (-V) displays version information.
163 Fixed problem in file-update system.
165 Fixed problem in shadow system; register was sometimes corrupted after
170 Fixed problems in the ISAM subsystem. Caused difficulties when updating
173 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
174 the rank and record number.
176 Fixed bug in the isam subsystem - caused a malfunction when accessing
177 words which occurred more than 10000 times.
179 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
182 Server can now run under inetd. Use option -i, and -w <directory> to
183 set working directory to desired location.
185 New zebraidx command: clean - removes temporary shadow files.
187 Fixed bug in ISAM system. Occurred rarely during register updates.
189 Logging during index merge phase is improved. The remaining running
192 Temporary files generated by zebraidx are removed after each run.
194 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
195 when doing scan operations in dictionaries with European characters.
199 A whole slew of updates, to make the first publicized release. Get the doc
204 Memory-problems in ISAM fixed. More blocktypes added to the default setup
205 to increase performance on larger databases.
207 Various minor changes in data management system.
211 A couple of portability-problems resolved.
213 Changed some malloc() to xmalloc().
