HuperDuperSynonymsFilter™
-------------------------
Key: LUCENE-3233
URL: https://issues.apache.org/jira/browse/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()
