---------------------------------
spatialdist() ?
We really need this.

> I've been thinking about how spatial support is exposed to Solr users.
> Presently there's the older Solr 3 stuff, most prominently seen via \{!geofilt} and \{!bbox} done by [~gsingers] (I think). and then there's the Solr 4 fields using a special syntax parsed by Lucene 4 spatial that looks like mygeofield:"Intersects(Circle(1 2 d=3))" What's inside the outer parenthesis is parsed by Spatial4j as a shape, and it has a special (non-standard) syntax for points, rects, and circles, and then there's WKT. I believe this scheme was devised by [~ryantxu].
> I'd like to devise something that is both comprehensive and is aligned with standards to the extent that it's prudent. The old Solr 3 stuff is not comprehensive and not standardized. The newer stuff is comprehensive but only a little based on standards. And I think it'd be nicer to implement it as a Solr query parser. I'll say more in the comments.
