Key: LUCENE-3220 URL: https://issues.apache.org/jira/browse/LUCENE-3220 Project: Lucene - Java Issue Type: New Feature Components: core/search Affects Versions: flexscoring branch Reporter: David Mark Nemeskey Assignee: David Mark Nemeskey With [LUCENE-3174|https://issues.apache.org/jira/browse/LUCENE-3174] done, we can finally work on implementing the standard ranking models. Currently DFR, BM25 and LM are on the menu. TODO: * `EasyStats`: contains all statistics that might be relevant for a ranking algorithm * `EasySimilarity`: the ancestor of all the other similarities. Hides the DocScorers and as much implementation detail as possible * _BM25_: the current "mock" implementation might be OK * _LM_ * _DFR_ Done: -- This message is automatically generated by JIRA.
