> Key: LUCENE-5529
> URL: https://issues.apache.org/jira/browse/LUCENE-5529
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/spatial
> Reporter: David Smiley
> Assignee: David Smiley
> Priority: Minor
> Fix For: 4.8
>
> Attachments: LUCENE-5529_Skip_redundant_non-point_scanned_cells.patch
>
>
> When searching for indexed non-point shapes (such as polygons), there are
> redundant cells which can be skipped at the bottom "detail level" of the
> search. This won't be a problem once LUCENE-4942 is fixed since there then
> won't be any but it's easy to fix now.
> This affects all predicates RecursivePrefixTreeStrategy uses except Contains.
