Robert Muir commented on LUCENE-3233:
-------------------------------------

bq. New patch, including some optimizing to FST (which we can commit under a separate issue)

works! I don't think we need to open a new issue, I didn't think you would come back with
a patch in just two hours!

I'll play with the patch some now and see what I can do with it.

> 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()
