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.

Subject: R-trees in Lucene for spatio-textual search

 

Hi, 

   Has anybody recently used lucene to implement R-trees for range-queries.
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
