For now, it's up to your app to know, unfortunately :-( I think the
WikipediaTokenizer is the only one using flags currently in the Lucene.

I'll use Token flags to specifiy first token in a sentence, but how
it's works? how flag collision is avoided? to keep it simple, i'll
take 1 as flag, but what happens if an other filter use the same
flags?

I think you need sentence detection to take place further
upstream. Then you could use the Token type or Token flags to
indicate punctuation, sentences, whatever and we could patch the
shingle filter to ignore these things, or break and move onto the
next one.

The newly ShingleFilter is very helpful to fetch group of words,
but it doesn't handle ponctuation or any separation.
If you feed it with multiple sentences, you will get shingle that
start in one sentences and end in the next.
In order to avoid that, you can handle token positions, if there
is more than one char with the previous token, it should be
punctation (or typo).
Any suggestions to handle only shingle in the same sentence?
