The "SpatialSearchDev" page has been changed by DavidSmiley.
The comment on this change is: Reference geohash prefix filter for indexing variable number of points..
http://wiki.apache.org/solr/SpatialSearchDev?action=diff&rev1=1&rev2=2

--------------------------------------------------

  A geohash is a way of encoding lat/lon into a single field as a String.  As of https://issues.apache.org/jira/browse/SOLR-1586, it will be possible to create a geohash via FieldType, simply by passing in a Point (lat,lon).  Solr will do the work of converting the point to a geohash.
  
  See http://www.geohash.org and http://en.wikipedia.org/wiki/Geohash
+ 
+ If you need to index a multi-valued point field, say because you have a variable number of points per document, then check out https://issues.apache.org/jira/browse/SOLR-2155 which uses a hierarchical grid geohash prefix technique to efficiently filter documents by a geographic shape.
