Grant Ingersoll commented on SOLR-1131:
---------------------------------------
{quote}I imagine 99% of the users of Point will be those wanting straight 2D
geo search (limit by simple distance, or sort by simple distance).
I don't see how elevation would help in isolation since more accurate distance
measures would presumably need map info for driving distance.
I could see people wanting to store 3D points, etc, but they can do that
today.{quote}
But it's not like the code is any faster or more complicated and neither is the
interface the user sees (I'm sure most people know what a point is). If I have
a generic Point, now I have a Vector. With a Vector, I can do all kinds of
interesting things. But rather than fret over it, we can have both.
LatLonFieldType and PointFieldType.

> In a few special cases, it makes sense for a single "field" (the concept) to
> be indexed as a set of Fields (lucene Field). Consider SOLR-773. The
> concept "point" may be best indexed in a variety of ways:
> * geohash (sincle lucene field)
> * lat field, lon field (two double fields)
> * cartesian tiers (a series of fields with tokens to say if it exists within
> that region)
