David Mark Nemeskey updated LUCENE-3220: ---------------------------------------- Description: 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: was: With [LUCENE-3174|https://issues.apache.org/jira/browse/LUCENE-3174] done, we can finally work on implementing the standard ranking models.
