Subject [jira] [Created] (LUCENE-3233) HuperDuperSynonymsFilterâ„¢
Date Thu, 23 Jun 2011 14:01:47 GMT

                 Key: LUCENE-3233
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Robert Muir

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()
