------------------------------------
Summary: Spatial distance relevancy should use score of 1/distance
Key: LUCENE-4208
URL: https://issues.apache.org/jira/browse/LUCENE-4208
Project: Lucene - Java
Issue Type: New Feature
Components: modules/spatial
Reporter: David Smiley
Fix For: 4.0
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.
