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