Subject [jira] Commented: (SOLR-2268) Add support for Point in Polygon searches
Date Tue, 07 Dec 2010 03:11:09 GMT


Lance Norskog commented on SOLR-2268:

A second variation: a multiValued field of vertex pairs which contain a polygon. The incoming
point searches for vertex point. This is faster than the bitwise filter, but uses more space
for larger polygons. The bitwise filter uses constant memory for each document.

 Solr could support two forms of this: 
> # A field contains a polygon and the user supplies a point.  If it does, the doc is returned.
> # A document contains a point and the user supplies a polygon.  If the point is in the
polygon, return the document
> With both of these case, it would be good to support the negative assertion, too.
