I'm using NOT_ANALYZED because I have a list of text items to index where some of the items are single words and some of the items are two words or more with punctuation. My problem is that sometimes one of the words in a item with two or more words matches one of the single text items. That sounds confusing so here is an example of the list:
info:name info:name, paul info:name, unknown info:unknown So here I have four items in the list. If I index this ANALYZED and do a search for "info:unknown", I will get two hits where I only wanted one. If I do a search for "info:name" I will get three hits where I only wanted one. I index using the StandardAnalyzer. I also index everything as ANALYZED into a "content" field for broad searches. That functions as expected. This is a specialized search where the user can search on field name (in this case "info"). The specialized search is not restricted to exact matches so the KeywordAnalyzer is out. I'm trying to allow searching on terms, phrases, and ranges as well as allowing fuzzy, wildcard, slop, and boost modifiers. I'm making use of the TermQuery, PhraseQuery, FuzzyQuery, WildcardQuery, TermRangeQuery and BooleanQuery. Using these classes produces better results than simply feeding a Query object to the QueryParser. Everything works as expected except for phrases because of the NOT_ANALYZED flag. Is there a KeywordQuery class? I think that would solve my problem.

NOT_ANALYZED stores the entire input as a *single* token, so you can never match on anything except the entire input. What did you hope to accomplish by indexint NOT_ANALYZED? That's actually a pretty specialized thing to do, perhaps there's a better way to accomplish your goal.
