It sounds like TermVectors may apply here?
The TermVectors for a doc are like a miniature inverted index just for
that one document. It lets you retrieve all terms and their
frequencies, plus optionally offset and positions information for each
term occurrence.

Very Thanks. But I'm sorry I can not catch what's your meaning.
A sentence through Analyzer.TokenStream method and will get a TokenStream
result. this TokenStream will save into index with someway, now I'm just to
get all token for this input sentence from index.
my english is very pool, maybe my artical can not easy to understand, so
sorry...

I like your nick name.
For the question, I think you must iterate all the terms in index with
TermEnum and see if term will satisfy any of your concerns.
