Subject Re: Geographical indexing in Lucene

Great work, Evgeny!

I'm certainly interested in this area and will be dissecting this in 
some detail.

I've done similar work before but making use of JTS (Java Topology 
Suite), using the OpenGIS standards for spatial features/queries and 
2-pass spatial queries (first rough pass is MBB only, 2nd pass does full 
geometry tests but only for results that satisfied any Lucene-text 
queries). What I haven't addressed (which you have here) is disk-based 
spatial indexes which is obviously the key to scalability.

Should have more to discuss once I've dug deeper in...
I for one would be interested in making this part of Lucene.

Thanks again,
