1 Fixed two bugs in ISAMC system.
3 Changed the way Zebra keeps its maintenance information. Records
4 in "SGML" notation using an EXPLAIN schema is now used when
7 Bug fix: Index didn't handle update/insert/delete of the same
8 record (i.e. same recordId) in one run (one invocation of zebraidx).
9 Only the first occurence of a record is considered.
11 Most searches now return correct number of hits.
13 New modular ranking system. Interested programmers are encouraged to
14 inspect rank1.c and improve the algorithm.
16 Bug fix: Lock files weren't removed as they should when using NT.
18 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
19 specify a "sort register". Refer to the gils sample records which
20 refer to index type "s" which is specified as "sort" in the default.idx
21 file. Each sort criteria can either be Ascending or Descending and
22 at most three sort elements can be specified.
24 Bug fix: Character mapping didn't work for text files.
28 Simple ranked searches now return correct number of hits.
30 The test option (-s) only makes a read-lock on the index as well
31 as using read-only operations anywhere.
33 Moved towards generic character mapping. Configuration file default.idx
34 specifies character map files for register types w, p, u, etc.
36 Implemented "begin variant" for the sgml.regx - filter.
38 Fixed a few memory leaks.
40 Added support for C++, headers uses extern "C" for public definitions.
42 Bug fix: The show records facility (-s) only displayed information for
43 the first record in a file (and not for every record in the file).
45 Added option "-f <n>" to limit the logging of record operations. After
46 <n> records has been processed no logging is performed (unless errors
49 Bug fix: the compressed ISAM system didn't handle update operations
52 Added setting, "maxResultSetSize", to hold the number of records to
55 Bug fix: Complete phrase did't work for search operations.
57 Bug fix: temporary result sets weren't deleted.
59 Reduced disk space for saved keys (storeKeys = 1).
61 Added optional, physical ANY (key replication)
63 Implemented proximity operator in search.
65 Bug fix: the path name buffers used by file match traversal routines
66 have been extended to support long file names.
68 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
69 configuration file. The resulting register without "storeKeys" is about
70 half the size, and the memory used by zebraidx during phase 2 (merge) is
73 Reworked the way Regexp-2 queries with error tolerance are handled and
74 specified. The documentation has been updated accordingly.
76 Bug fix: Zebrasrv didn't search correctly when queries contained masking
77 characters. This bug was introduced in 1.0a8.
79 Zebrasrv now tag records with the proper database name.
81 New settings, memMax and keyTmpDir.
83 Changed name of setting lockDir (previously called lockPath) and
84 setTmpDir (previously called tempSetPath).
86 Generalized and changed record type specifications. In short, there are:
88 grs.sgml structured, "SGML-like" syntax
89 grs.regx.<filter> structured, Regular expression filter
90 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
91 is the name of an abstract syntax file.
92 Bug fix: Result sets weren't sorted in operations involving boolean
93 operations with "ranked" operands.
97 Added national character-handling subsystem.
101 Small modifications to input filters and profiles.
103 Added support for SOIF syntax (with private OID).
107 Fixed buffer-size problem in indexing.
109 Added compression to temporary files for updating.
111 Added phrase registers.
113 Added dynamic mapping of search attribute to multiple termlists (ANY).
115 Scan support in multiple databases/registers.
117 Configuration settings are case-insensitive and single dash (-)
118 characters are ignored in comparisons.
120 The index processing ignores empty files - warning given.
122 New option to zebraidx (-V) displays version information.
126 Fixed problem in file-update system.
128 Fixed problem in shadow system; register was sometimes corrupted after
133 Fixed problems in the ISAM subsystem. Caused difficulties when updating
136 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
137 the rank and record number.
139 Fixed bug in the isam subsystem - caused a malfunction when accessing
140 words which occurred more than 10000 times.
142 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
145 Server can now run under inetd. Use option -i, and -w <directory> to
146 set working directory to desired location.
148 New zebraidx command: clean - removes temporary shadow files.
150 Fixed bug in ISAM system. Occurred rarely during register updates.
152 Logging during index merge phase is improved. The remaining running
155 Temporary files generated by zebraidx are removed after each run.
157 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
158 when doing scan operations in dictionaries with European characters.
162 A whole slew of updates, to make the first publicized release. Get the doc
167 Memory-problems in ISAM fixed. More blocktypes added to the default setup
168 to increase performance on larger databases.
170 Various minor changes in data management system.
174 A couple of portability-problems resolved.
176 Changed some malloc() to xmalloc().
