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

    [ https://issues.apache.org/jira/browse/SOLR-2268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12968556#action_12968556
] 

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.

> In spatial applications, it is common to ask whether a point is inside of a polygon.
 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.
