Grant Ingersoll updated SOLR-1131:
----------------------------------
Attachment: SOLR-1131.patch
OK, this is getting a lot closer to ready to commit.
Changes:
# Introduced a MultiValueSource - ValueSource that abstractly represents
ValueSources for poly fields, and other things.
# Introduced PointValueSource - point(x,y,z) - a MultiValueSource that wraps
other value sources (could be called something else, I suppose)
# Implemented PointTypeValueSource to represent ValueSource for the PointType
class.
# Hooked in multivalue callbacks to DocValues. In addition to making functions
work with Points (et. al) it should be possible to write functions that work on
multivalued fields, but I did not undertake this work.
# Add in SchemaAware callback mechanism so that Field Types and other schema
stuff can register dynamic fields, etc. after the schema has been created
# Updated the example to have spatial information in the docs, etc. See
http://wiki.apache.org/solr/SpatialSearch
# Modified the distance functions to work with MultiValueSources
# cleaned up the tests
# Incorporated various comments from Chris and Yonik.
> Allow a single field type to index multiple fields

> 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)
