Thanks for the input. I'll give the WhitespaceAnalyzer a shot. Also, AFAIK, Field.Index.NOT_ANALYZED means that the content you index is not split into separate tokens so it is searchable, but only for exact matches. I may be able to get what I want with the WhitespaceAnalyzer and Field.Index.NOT_ANALYZED. Thanks again.

I also only want exact hits, so that analyzer works well for me. Also, AFAIK you don't set NOT_ANALYZED if you want to search through it.
