Records +in "SGML" notation using an EXPLAIN schema is now used when +appropriate. + +Bug fix: Index didn't handle update/insert/delete of the same +record (i.e. same recordId) in one run (one invocation of zebraidx). +Only the first occurence of a record is considered. + +Most searches now return correct number of hits. + +New modular ranking system. Interested programmers are encouraged to +inspect rank1.c and improve the algorithm. + +Bug fix: Lock files weren't removed as they should when using NT. + +Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to +specify a "sort register". Refer to the gils sample records which +refer to index type "s" which is specified as "sort" in the default.idx +file. Each sort criteria can either be Ascending or Descending and +at most three sort elements can be specified. + +Bug fix: Character mapping didn't work for text files. + +--- 1.0b1 1998/1/29 + +Simple ranked searches now return correct number of hits. + +The test option (-s) only makes a read-lock on the index as well +as using read-only operations anywhere. + +Moved towards generic character mapping. Configuration file default.idx +specifies character map files for register types w, p, u, etc. + +Implemented "begin variant" for the sgml.regx - filter. + +Fixed a few memory leaks. + +Added support for C++, headers uses extern "C" for public definitions. + +Bug fix: The show records facility (-s) only displayed information for +the first record in a file (and not for every record in the file). + +Added option "-f " to limit the logging of record operations. After + records has been processed no logging is performed (unless errors +occur). + +Bug fix: the compressed ISAM system didn't handle update operations +correctly. + +Added setting, "maxResultSetSize", to hold the number of records to +save in a result set. + +Bug fix: Complete phrase did't work for search operations. + +Bug fix: temporary result sets weren't deleted. + +Reduced disk space for saved keys (storeKeys = 1). + +Added optional, physical ANY (key replication) + +Implemented proximity operator in search. + +Bug fix: the path name buffers used by file match traversal routines +have been extended to support long file names. + +New C(ompressed) ISAM system. To enable it, specify "isam: c" in the +configuration file. The resulting register without "storeKeys" is about +half the size, and the memory used by zebraidx during phase 2 (merge) is +reduced to a minimum. + +Reworked the way Regexp-2 queries with error tolerance are handled and +specified. The documentation has been updated accordingly. + +Bug fix: Zebrasrv didn't search correctly when queries contained masking +characters. This bug was introduced in 1.0a8. + +Zebrasrv now tag records with the proper database name. + +New settings, memMax and keyTmpDir. + +Changed name of setting lockDir (previously called lockPath) and +setTmpDir (previously called tempSetPath). + Generalized and changed record type specifications. In short, there are: text plain SUTRS grs.sgml structured, "SGML-like" syntax grs.regx. structured, Regular expression filter - + grs.marc. Reads *MARC records in the ISO2709 format. + is the name of an abstract syntax file. Bug fix: Result sets weren't sorted in operations involving boolean operations with "ranked" operands.
