Ryan McKinley commented on SOLR-773:
------------------------------------
Yonik -- I like all 4 proposals.
I am not familiar with the function query internal -- would it get called for
things that do not match the filter? Distance calculations are typically the
most expensive part of the query.
re "It seems like points should be stored and represented in a single field..."
-- I agree that the schema and URL API should point to a single field to
represent the geometry field. In practice, the indexing will probably need
multiple fields to get the job done (efficiently).
It would be great if the schema field type could define everything needed to
index and search. There are (at least) three approaches to indexing points
that each have their advantages (and disadvantages) -- we should be able to
support any of these options.
{panel}
* GeoPointField (abstract? the standard stuff about dealing with points)
** GeoPointFieldHash (represented as a GeoHash, fast bounds query (with
limited accuracy))
** GeoPointFieldTiers (highly scalable, fast, complex)
** GeoPointFieldTrie (...)
* GeoLineField...
* GeoPolygonField...
{panel}
I think it makes sense to try to follow the [georss|http://georss.org/simple]
format to represent geometry:
{code:xml}
<georss:point>45.256 -71.92</georss:point>
{code}
{code:xml}
<georss:line>45.256 -110.45 46.46 -109.48 43.84 -109.86</georss:line>
{code}
{code:xml}
<georss:polygon>
45.256 -110.45 46.46 -109.48 43.84 -109.86 45.256 -110.45
</georss:polygon>
{code}
{code:xml}
<georss:box>42.943 -71.032 43.039 -69.856</georss:box>
{code}
