David Smiley updated LUCENE-4208:
---------------------------------
Attachment:
LUCENE-4208_makeQuery_return_ConstantScoreQuery,_standardize_makeDistanceValueSource_behav.patch
Patch with these changes:
* makeValueSource is makeDistanceValueSource to make abundantly clear. And it
takes Point instead of SpatialArgs.
* Standardized behavior of makeDistanceValueSource across the 3 strategies,
including null value behavior (it's '180' if geo, Double.MAX_VALUE otherwise).
* Tests for makeDistanceValueSource in DistanceStrategyTest
* Added final method SpatialStrategy.makeRecipDistanceValueSource(queryShape)
including tested it. This addresses the title of this JIRA issue.
I'll put off overhauling TwoDoubles into another JIRA issue. I've already done
some work for that.
> Spatial distance relevancy should use score of 1/distance

> The SpatialStrategy.makeQuery() at the moment uses the distance as the score
> (although some strategies -- TwoDoubles if I recall might not do anything
> which would be a bug). The distance is a poor value to use as the score
> because the score should be related to relevancy, and the distance itself is
> inversely related to that. A score of 1/distance would be nice. Another
> alternative is earthCircumference/2 - distance, although I like 1/distance
> better. Maybe use a different constant than 1.
