Hi Dev,
I've read very interesting interview with Ryan, http://www.lucidimagination.com/Community/Hear-from-the-Experts/Podcasts-and -Videos/Interview-Ryan-McKinley Another finding is https://issues.apache.org/jira/browse/SOLR-773 (lucene/contrib/spatial) Is there any more staff going on for SOLR 1.5 (and existing SOLR 1.4)? I need filtering on 2-dimension like x:[10000 TO 10100] y:[7900 TO 8000] (that's why I need SOLR:))) Any thoughts? I'd love to implement something quick-simple-efficient if it doesn't exist yet, like R-Tree (http://en.wikipedia.org/wiki/R-tree), or Geohash (http://en.wikipedia.org/wiki/Geohash) I haven't tried "Local Lucene" and SOLR-773 yet.
