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