Yonik Seeley commented on SOLR-1586:
------------------------------------

bq. I'm not sure I see how to use a tile for anything other than filtering 

That's the point though - as a casual user, I want a point field.  I want to be 
able to do efficient spacial search on that field and not worry about all of 
the details.  See the example I gave above... it's doing everything 
spacial-related on the *same* field.  So a higher level SpacialTilePoint would 
be a point field (i.e. it would still have lat/lon separately) that used tiles 
under the cover for efficient bounding box / filters.

bq. The choice of the data structure is going to depend on the application

There will often be many applications / clients.  One should be able to change 
the underlying implementation and use the same requests.  We can do this today 
with range queries on any type of numeric field... we should be able to do it 
with a bounding box or distance filter.

> Per SOLR-773, create field types that hid the details of creating tiers, 
> geohash and lat/lon fields.
> Fields should take in lat/lon points in a single form, as in:
> <field name="foo">lat lon</field>
