------------------------------------
Summary: Spatial CellTokenStream re-use
Key: LUCENE-5776
URL: https://issues.apache.org/jira/browse/LUCENE-5776
Project: Lucene - Core
Issue Type: Improvement
Components: modules/spatial
Reporter: David Smiley
It would be nice if CellTokenStreams were re-used, which are kinda heavy. This
is possible without changing the API thanks to LUCENE-5634.
PrefixTreeStrategy.createFields() should return Field subclasses that override
{{TokenStream tokenStream(Analyzer analyzer, TokenStream reuse)}} that in turn
examine re-use to ensure it's a CellTokenStream, and then re-use it if possible
or create anew.
Completing the re-use, it would be good if TreeCellIterator could be re-used,
which might include the getWorldCell value.
