Michael McCandless updated LUCENE-3233:
---------------------------------------
Attachment: LUCENE-3233.patch
New patch, folding in Robert's changes and the random stress test. All tests
pass. I think it's now functionally correct, but I still need to compare perf
vs existing syn filter, and there are still a few minor nocommits to work out.
Ideally, if we get perf close enough, since RAM is much much less w/ this new
syn filter, I think we should replace the old one with this new one.

> The current synonymsfilter uses a lot of ram and cpu, especially at build
> time.
> I think yesterday I heard about "huge synonyms files" three times.
> So, I think we should use an FST-based structure, sharing the inputs and
> outputs.
> And we should be more efficient with the tokenStream api, e.g. using
> save/restoreState instead of cloneAttributes()
