Subject [jira] [Commented] (LUCENE-4895) Implement Spatial "disjoint" predicate.
Date Tue, 02 Apr 2013 02:43:16 GMT


David Smiley commented on LUCENE-4895:

Yeah, I agree.  Some apps will always have spatial data in a field and so calculating IsSpatial()
is redundant, though I suppose that's not a big deal if it's cached.  Where shall that be
cached? Hmmm.

> 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.
