In the Lucene context you simply have tokens. In the analyzed case (i.e. text), the token is however the incoming stream is split up by the analysis chain you construct. In the string case the token is the entire input. That’s just the way it works.
You have two choices: 1> Use two fields, one text-based and one string based. Your query puts the search text against whichever one is appropriate. I’ll add that if you want to use limited analysis, say lowercasing the entire input string, use a text-based field with something like KeywordTokenizer + LowerCaseFilter rather than a string field. 2> Use a text field and do phrase searching when you want the whole thing to match. The flaw here is that if the text were “my dog has fleas” and you searched for “my dog” (as a phrase), you’d get a match. You can get around that by adding another field with the word count and then search something like “my dog” AND word_count:2.
