[jira] [Updated] (LUCENE-4895) Implement Spatial "disjoint"
predicate.
[ https://issues.apache.org/jira/browse/LUCENE-4895?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Smiley updated LUCENE-4895:
---------------------------------
Attachment: LUCENE-4895_Spatial_Disjoint_predicate.patch
Attached is a generic Filter implementing the disjoint predicate in terms of a provided SpatialStrategy's support for intersects, as well as field designated to determine which docs have spatial data via the FieldCache.
I have yet to integrate this with the existing strategies and test it because such things would conflict with an outstanding spatial issue pending to be committed tonight. So I'll do these things tomorrow.

> The "IsDisjointTo" SpatialOperation is not implemented for RecursivePrefixTreeStrategy and some/all others(?). It has been very low priority because it is simply the inverse of "Intersects" which is universally implemented on the SpatialStrategy implementations.
> * Should spatial "disjoint" count documents that have no spatial data?
> * Arguably, there should be one implementation amongst the SpatialStrategies implemented in terms of "Intersects"; this way each strategy need not deal with it.
