I did an little experiment with a Geohash/Geocells https://github.com/integrallis/geomodel (a poor port of a Python Geohash librairy) and using Cassandra in a demo using public schools data here https://github.com/integrallis/geomodel-cassandra-demo
My conclusions is that you can use the Geohash natural lexicographic ordering with Cassandra partition keys to do range queries and also simulate radius searches, but to make it work I had to do some goofy amount of data replication. I'll go back to it and refactor when I have time to see if I can improve the whole thing. Adding a regular search engine into the equation might help, I was also thinking of using C* Triggers to do the data replication needed for the searchers.
