Subject [jira] [Commented] (SOLR-2268) Add support for Point in Polygon searches
Date Thu, 21 Apr 2011 23:29:06 GMT


Alexander Kanarsky commented on SOLR-2268:


in addition to David's work (SOLR-2155) you can also try my polygon extension for the JTeam's
(Chris Male et al) Spatial Solr Plugin (SSP). The SSP is a standalone Solr module that works
with Solr 1.4.x, you can get it here: 

It allows Radius search for the lat,lon documents. 

The polygon/polyline extension for SSP 2.0 in addition to this allows polygon search. It is
located here:

There has some limitations (for example, plane geometry is used) but it may work just well
for you, depending on your situation.

> 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.
