Subject [jira] [Updated] (LUCENE-3233) HuperDuperSynonymsFilterâ„¢
Date Wed, 06 Jul 2011 05:26:16 GMT


Robert Muir updated LUCENE-3233:

    Attachment: LUCENE-3233.patch

Updated patch:
* added a SolrSynonymsParser and test to the analyzers module, that parses the existing solr
synonyms format.
* added a Solr factory for this thing (untested!) that uses this when "format=solr" (the default)

This way, the idea is the factory would be more extensible, e.g. you could load syns from
a database, or we could add parsers for wordnet and nuke contrib/wordnet, etc etc.

Still need to do some basic benchmarking.

> 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()
