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