: I would think I could index a lat,lon pair into a GeoHashField (that
: works) and then retrieve the field value to see the computed geohash.
...
: What am I missing - how can I retrieve the hash?
I don't think it's designed to work that way.
GeoHashField provides GeoHash based search support for lat/lon values
through it's internal (indexed) representaiton -- much like TrieLongField
provides efficient range queries using trie encoding -- but the "stored"
value is still the lat/lon pair (just as a TrieLongField is still the long
value)
If you want to store/retrive a raq GeoHash string, i think you have to
compute it yourself (or put the logic in an UpdateProcessor).
org.apache.lucene.spatial.geohash.GeoHashUtils should take care of all the
heavy lifting for you.
