ASF subversion and git services commented on LUCENE-7942: --------------------------------------------------------- Commit fe766452132c0260198a9516094278ff84ac55e6 in lucene-solr's branch refs/heads/branch_7x from [~kwri...@metacarta.com] [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=fe76645 ] LUCENE-7942: Add aggregateDistances() method to DistanceStyle, and use it in GeoStandardPath to aggregate distances from segment to segment. > For Geo3d paths, aggregating distance values using "+" is not adequate for > squared distances > -------------------------------------------------------------------------------------------- > > Key: LUCENE-7942 > URL: https://issues.apache.org/jira/browse/LUCENE-7942 > Project: Lucene - Core > Issue Type: Bug > Components: modules/spatial3d > Reporter: Karl Wright > Assignee: Karl Wright > > The GeoStandardPath object aggregates distances segment by segment using > simple addition. For some kinds of Distance computations, though, addition > is not an adequate way to do this. The xxxSquaredDistance computations, for > example, do not produce true squared distances but rather a distance metric > that is a combination of both squared and linear. > I propose adding support in Distance for aggregation, which would allow > distance calculators to compute an accurate distance (at some computational > cost) instead. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
