R-trees are for spatial queries (two dimensions). If you want to have the same for one-dimensional range queries, use TrieRangeQuery (see 2.9's contrib queries package, this may move to core as a NumericRangeQuery etc.), which is very stable and tested since years, but now to be included in Lucene.

I came across the GeoLucene project but not sure how stable/efficient it is to use it for production. Any pointers in this direction will be great. Thanks -P
