David Smiley commented on LUCENE-4342: -------------------------------------- Thanks for the bug report. I think there may be a level off-by-one error, so maybe that's it, but I haven't doug into your bug report yet but will soon. > Issues with prefix tree's Distance Error Percentage > ---------------------------------------------------- > > Key: LUCENE-4342 > URL: https://issues.apache.org/jira/browse/LUCENE-4342 > Project: Lucene - Core > Issue Type: Bug > Components: modules/spatial > Affects Versions: 4.0-ALPHA, 4.0-BETA > Reporter: Itamar Syn-Hershko > Assignee: David Smiley > Attachments: unnamed.patch > > > See attached patch for a failing test > Basically, it's a simple point and radius scenario that works great as long > as args.setDistPrecision(0.0); is called. Once the default precision is used > (2.5%), it doesn't work as expected. > The distance between the 2 points in the patch is 35.75 KM. Taking into > account the 2.5% error the effective radius without false negatives/positives > should be around 34.8 KM. This test fails with a radius of 33 KM. -- This message is automatically generated by JIRA.
