Chris Male commented on LUCENE-4208: ------------------------------------ I'm considered this obfuscates the actual distance too much, making it difficult to retrieve x again. It's not impossible but suddenly anybody wanting to retrieve the actual distance must calculate c again. > Spatial distance relevancy should use score of 1/distance > --------------------------------------------------------- > > Key: LUCENE-4208 > URL: https://issues.apache.org/jira/browse/LUCENE-4208 > Project: Lucene - Core > 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. > Credit: this is Chris Male's idea. -- This message is automatically generated by JIRA.
