dtsWlbListFields = 0x0100	In dtsWordListBuilder, include field names in the output.
dtsSearchWantHitsByWord2 = 0x0400	Deprecated. Use dtsSearchWantHitDetails instead.

dtsSearchDelayDocInfo = 0x1000	Optimize search by waiting until document records are requested through a search results object before reading them from the index. See dtsSearchDelayDocInfo in the Overviews section.
dtsSearchExternalSynonyms = 0x2000	Enable synonym expansion using an external thesaurus. See Synonym search settings.
