Subject [jira] Commented: (LUCENE-2617) coord should still apply to missing terms/clauses
Date Tue, 24 Aug 2010 13:52:16 GMT

Michael McCandless commented on LUCENE-2617:
--------------------------------------------

Are we sure that non-existent terms/phrases should contribute to coord?  I have no idea which
way is "right" ;)  I'm just asking...

bq. Anyone know if null is actually ever returned from Weight.scorer() in 2.9?

Hmm LUCENE-1754 was fixed in 2.9?  Didn't in bring allowed null return from Weight.scorer()?

> Missing terms in a boolean query "disappear" (i.e. they don't even affect the coord factor).
