Hi,
In the early Solr 1.3 times we had an index with leisure-time objects that included geographical coordinates. Based on certain conditions we had to display a specific list of nearby objects. We simply implemented some Great Circle calculations such as the distance between points [1] and aggregated nearby objects and sent then to our index. The drawback is that for each addition to the index, you'd have to recalculate all other nearby objects, that takes a while. The good thing is, in production, the system isn't slowed down by these calculations so it's very fast.

I have been partitioning the whole Solr thing to him,except enough info for me to understand and interface to his work. Sooooooooo, I don't have that answer. Can someone else answer him?
