David Smiley updated SOLR-3304:
-------------------------------
Attachment: SOLR-3304_Solr_fields_for_Lucene_spatial_module.patch
Attached is the first draft.
The Solr support for the new Lucene spatial module is a set of field types
which are effectively adapters into the real logic in Lucene. Even all the
configuration option initialization from the fieldType attributes are done in
Lucene. A map of these is passed with a utility wrapper to detect which
attributes were seen so that they can be removed afterwards. And so if you typo
a parameter then you'll get an error like you would for any other field type.
The Lucene spatial module supports sorting indirectly by having a spatial
Query's score be the distance. Of course you don't always need the
score/distance and so there is a local-param attribute needScore which can be
set to false, such as in a filter query (see SOLR-2883).
I'll say the tests here are so-so; I welcome input on how they can be
structured to be more effective. Since the real logic is all in the Lucene
spatial module, ideally the tests on the Solr side would be fairly minimal in
this regard... just instantiate the various field types exercising a few
features and a few options.
Some TODOs:
* Document how to use it in the wiki
* At least some basic tests for the SpatialTwoDoublesFieldType and
SpatialTermQueryPrefixTreeFieldtype.
At least for now, I don't envision the capabilities here replacing the Solr
spatial introduced in 3x; it is a new alternative.
