>
> 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.
