David Smiley updated LUCENE-2765:
---------------------------------
Fix Version/s: (was: 4.7)
4.8
> Optimize scanning in DocsEnum
> -----------------------------
>
> Key: LUCENE-2765
> URL: https://issues.apache.org/jira/browse/LUCENE-2765
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Robert Muir
> Assignee: Robert Muir
> Fix For: 4.8
>
> Attachments: LUCENE-2765.patch, LUCENE-2765.patch
>
>
> Similar to LUCENE-2761:
> when we call advance(), after skipping it scans, but this can be optimized
> better than calling nextDoc() like today
> {noformat}
> // scan for the rest:
> do {
> nextDoc();
> } while (target > doc);
> {noformat}
> in particular, the freq can be "skipVinted" and the skipDocs (deletedDocs)
> don't need to be checked during this scanning.
