Looking at the example schema: http://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_3_3/solr/example/solr/conf/schema.xml
the solr.PointType field type uses double (is this just an example field, or used for geo search?), while the solr.LatLonType field uses tdouble and it's unclear how the geohash is translated into lat/lon values or if the geohash itself might typically be used as a copyfield and use just for matching a query on a geohash? Is there an advantage in terms of speed to using Trie fields for solr.LatLonType? I would assume so, e.g. for bbox operations. Thanks, Peter -- Peter M. Wolanin, Ph.D. : Momentum Specialist, Acquia.
