Subject [jira] Commented: (LUCENE-2694) MTQ rewrite + weight/scorer init should be single pass
Date Thu, 18 Nov 2010 18:50:16 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933522#action_12933522

Simon Willnauer commented on LUCENE-2694:
-----------------------------------------

Uwe I agree with your comments - I just didn't pay lots of attention to it since I was rather
interested in feedback for the idea....

I actually think that we should move the getTermState into the termsEnum though rather than
using an attribute but for now that was easier to implement though.

bq. What happens in the term collectors when the same term with different states are merged
in the PQ/TermsHash/...?
That one should work since I map the TermState per reader in a PerReaderTermState though.

> 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.
