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

                 Key: LUCENE-1512
                 URL: https://issues.apache.org/jira/browse/LUCENE-1512

            Reporter: patrick o'leary
            Priority: Minor


Based on comments from Yonik and Ryan in SOLR-773
GeoHash provides the ability to store latitude / longitude values in a single field consistent hash field.

Ryan McKinley commented on LUCENE-1512:
---------------------------------------

Any chance you could make a new patch without SerialChainFilter moved to search?

Should we make a new package for geohash based things?
org.apache.lucene.spatial.geohash
 - GeoHashUtils
 - GeoHashDistanceFilter

Also, the spacing for GeoHashUtils should be 2 spaces rather then 4.

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

Thanks patrick!

I just committed this, the only change is that I used StringBuilder rather then StringBuffer.

The precision is hard coded to 12 -- perhaps we could make that a variable?
