Grant Ingersoll commented on SOLR-1586:
---------------------------------------
bq. Unlike PointType, it seems odd that a user would need to understand and
declare any kind of subFieldTyp/Suffiix for SpatialTileField... seems like this
one we really want to be an implementation detail somehow..
I suppose they could just always be a DoubleField subtype, but how do you
guarantee it is registered in the schema? I suppose it is 99.99% likely it
will be there, so we could just assume it. I can change it to do this.
bq. and ultimately it seems like we want to allow the SpacialTileFIeld to be an
implementation detail as well. It would be nice to just define a
SpacialTilePoint and just use it for everything (filtering, distance
calculations, etc).
I'm not sure I see how to use a tile for anything other than filtering (is the
point in the box or not). I suppose it could be used for vary crude distance
calculations, but that doesn't seem all that useful. I think there may be too
much of a goal to hide all the details from the application. The choice of the
data structure is going to depend on the application, just as one chooses to
use int, float or double depending on their application needs. Many
applications will do just fine using PointType with a double, even for range
queries. Others may specifically want a tile approach as it best solves their
problem.

> 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>
