[Xapian-discuss] Can xapian do geo search/calculations?

[Joe Noon]

Im currently using sphinx, which has a nice geo searching interface:

If given a query and an origin (latitude, longitude, both in radians),
and told which fields correspond to latitude/longitude in the index, I
can get back results ordered by distance from that point (and get the
actual distance as well).

I would be interested in exploring xapian further, but I'm not sure if
I can get this functionality or not.  Ive been told it may be possible
with a a value range processor? Is this something anyone else has
already explored? Or know if it would even be possible?

Thanks,

Joe
