David Smiley commented on SOLR-1568:
------------------------------------
I have been testing the capabilities of this patch further. I am using
LatLonType and I have multiple points per document. It doesn't appear that the
logic in LatLonType properly handles multi-value fields since its doing range
queries for the latitude and longitude separately. I have a document with a
couple points it, Copenhagen Denmark and Ethiopia. If I query for points in
the box Lat: 10.8 - 5.4, and Lon: 9.50 - 14.23 then I find this document when I
shouldn't. This box is at a place south of Copenhagen and West of Ethiopia.
Oh by the way, I made some modifications after applying the patch so that I
could query by a lat-lon box instead of a point-radius. It was very easy.

> Given an index with spatial information (either as a geohash,
> SpatialTileField (see SOLR-1586) or just two lat/lon pairs), we should be
> able to pass in a filter query that takes in the field name, lat, lon and
> distance and produces an appropriate Filter (i.e. one that is aware of the
> underlying field type for use by Solr.
> The interface _could_ look like:
> {code}
> &fq={!sfilt dist=20}location:49.32,-79.0
> {code}
> or it could be:
> {code}
> &fq={!sfilt lat=49.32 lat=-79.0 f=location dist=20}
> {code}
> or:
> {code}
> &fq={!sfilt p=49.32,-79.0 f=location dist=20}
> {code}
> or:
> {code}
> &fq={!sfilt lat=49.32,-79.0 fl=lat,lon dist=20}
> {code}
