- Faster indexing of binary data using the filtering algorithm
- Fixes and minor enhancements:
- In dtSearch Desktop, added SizeK, IndexRetrievedFrom, SearchDate, ReportDate variables to SearchReportTemplate.rtf and SearchListTemplate.rtf

New in dtSearch Network with Spider 7.64.7876 (Apr 20, 2010)
- Enhancements (dtSearch Engine):
- Added dtsSearchLanguageAnalyzerSynonyms flag to enable using a language analyzer to generate morphological variations on a search term at search time. When this flag is set, the language analyzer is called for each word or phrase in the search request. The flag dtsLaInputIsSearchTerm is passed to the language analyzer in dtsLaJob.flags, so the language analyzer knows why it is being called.
- Added dtssGetWordBreaker API function to provide direct access to the dtSearch Engine's internal word breaker using the language analyzer API. For sample code demonstrating how to use this API, see the WordBreak example in examples\vc8\WordBreak.

- Fixed index merge bug causing "Inconsistent doc ids from target index" error during merge.
- Fixed two search report bugs causing incorrect hit highlighting.

- Compatibility notes for developers working with the .NET 2.0 API only:
- In dtSearch 7.63, the DLL dependencies for dtSearchNetApi2.dll have changed due to the release of the Visual Studio .NET 2005 Service Pack 1 Security Update for ATL.
