Zack Zullick commented on LUCENE-2899:
--------------------------------------
Some information for those wanting to try this after fighting it for a day: the
latest patch posted, LUCENE-2899-RJN.patch for 4.1 does not have Em's
OpenNLPFilter.java and OpenNLPTokenizer.java fixed applied. So after applying
the patch, make sure to replace those classes with Em's version or the bug that
causes the NLP system to only be utilized on the first request will still be
present. I was also able to successfully apply this patch to 4.2.1 with minor
modification (mostly to the build/ivy xml files).

> Now that OpenNLP is an ASF project and has a nice license, it would be nice
> to have a submodule (under analysis) that exposed capabilities for it. Drew
> Farris, Tom Morton and I have code that does:
> * Sentence Detection as a Tokenizer (could also be a TokenFilter, although it
> would have to change slightly to buffer tokens)
> * NamedEntity recognition as a TokenFilter
> We are also planning a Tokenizer/TokenFilter that can put parts of speech as
> either payloads (PartOfSpeechAttribute?) on a token or at the same position.
> I'd propose it go under:
> modules/analysis/opennlp
