Subject [jira] Commented: (LUCENE-2694) MTQ rewrite + weight/scorer init should be single pass
Date Thu, 18 Nov 2010 18:46:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933517#action_12933517
] 

Michael McCandless commented on LUCENE-2694:
--------------------------------------------

I would rather not use an attribute here -- this is a very core thing so I think we should
extend TermsEnum API.

We can just add a getTermState and a seek(TermState) to terms enum (and, actually, remove
cacheTermState)?

Also, then we wouldn't need to add the get docs/positions enum methods to TermState.

> Once we fix MTQ rewrite to be per-segment, we should take it further and make weight/scorer
init also run in the same single pass as rewrite.
