Hi, You can use Solr 1.4.1 and a third party plugin [1]. It does a pretty good job in spatial search. You could also try the Solr 3.1 branch which also has some spatial features on-board. It, however, does not return computed distances but can filter and sort using the great circle algorithm or a bounding box and also covers the problem of the poles.
I would migrate to the 3.1 branch first and see how 4.0 behaves when it is being released and got a few bugfix updates.
