Updates in V7.64

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.
  • Added more structural information to the output generated by conversion to the it_ContentAsXml file format.
  • Added to COM interface: WordListBuilder.ListFieldValues, WordListBuilder.SetFilter, and IndexJob.EnumerableFields.
  • Added dtsListIndexSkipNoiseWords flag for ListIndexJob to list words in an index without including any noise words.
  • Added dtsoFfSkipDataSourceFields flag for Options.FieldFlags to prevent DocFields values from appearing in FileConverter output

Fixes and minor enhancements
