Mark Harwood commented on SOLR-2268:
------------------------------------
bq.I would propose the following format: vertices are separated by semi-colons,
points are separated by commas
The spatially enabled databases follow the "Simple Features Specification for
SQL" spec which defines the ironically named "Well Known Text" format (WKT) for
representing points polygons etc
http://en.wikipedia.org/wiki/Well-known_text
bq. For PointType, we can just use capabilities of java.awt.Polygon
Using any AWT class can introduce issues related to servers and headless mode.
I'd recommend instead the JTS Java Topology Suite which has a lot of useful
stuff - including WKT readers and writers

>
> 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.
