Subject [jira] Commented: (LUCENE-1345) Allow Filter as clause to BooleanQuery
Date Sat, 10 Jan 2009 17:07:59 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12662673#action_12662673
] 

John Wang commented on LUCENE-1345:
-----------------------------------

Filters by definition (afaik) does not participate in scoring. Since "score gathering" is
done at the BooleanQuery level, does it mean BooleanQuery would need to do instanceof check
to see if it is a Filter? 

Or do we always hardcode filter with score 0? This is also dangerous if people do augment
scores at hitcollector level or score gathering logic changes to something not as straightforward
as summing.

my two cents.
