Subject [jira] Commented: (SOLR-773) Incorporate Local Lucene/Solr
Date Mon, 27 Apr 2009 18:14:30 GMT


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

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.   

 * 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...

I think it makes sense to try to follow the [georss|] format to represent
  <georss:point>45.256 -71.92</georss:point>

<georss:line>45.256 -110.45 46.46 -109.48 43.84 -109.86</georss:line>

	45.256 -110.45 46.46 -109.48 43.84 -109.86 45.256 -110.45

<georss:box>42.943 -71.032 43.039 -69.856</georss:box>

we should evaluate how best to incorporate it into Solr.
