Trejkaz updated LUCENE-1240:
----------------------------
Attachment: terms-filter.patch
Attaching my attempt at improving this.
The original code didn't close all the TermDocs it created either; this is now
fixed also.
> TermsFilter: reuse TermDocs
> ---------------------------
>
> Key: LUCENE-1240
> URL: https://issues.apache.org/jira/browse/LUCENE-1240
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Search
> Affects Versions: 2.3.1
> Reporter: Trejkaz
> Attachments: terms-filter.patch
>
>
> TermsFilter currently calls termDocs(Term) once per term in the TermsFilter.
> If we sort the terms it's filtering on, this can be optimised to call
> termDocs() once and then skip(Term) once per term, which should significantly
> speed up this filter.
