------------------------------------
Summary: spatial pointsOnly flag shouldn't force predicate to
Intersects
Key: LUCENE-6190
URL: https://issues.apache.org/jira/browse/LUCENE-6190
Project: Lucene - Core
Issue Type: Improvement
Components: modules/spatial
Reporter: David Smiley
Assignee: David Smiley
Fix For: 5.1
In the process of testing the pointsOnly flag, I realized RPT's optimization to
force the predicate to Intersects from Within|Contains isn't sound. In the
case of Within, this is only valid if there is one point per document but not
multiple (since _all_ points on a doc need to intersect the query shape), and
for Contains it was simply wrong.
Note that the strategy has no multi-valued hint or some-such. If it did, then
if !multiValued && pointsOnly, *then* Within could be changed to Intersects.
Regardless, swapping the predicate can be done at a higher level (Solr/ES).
