Subject [jira] Commented: (LUCENE-2454) Nested Document query support
Date Mon, 14 Jun 2010 20:59:15 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878741#action_12878741

David Smiley commented on LUCENE-2454:
--------------------------------------

That's an interesting strategy.  The size of these arrays is no big deal to me since there's
only a couple of them.  My concern with this strategy is that I wonder if potentially many
places in Solr would have to be become aware of this scheme which might make this strategy
untenable to implement even though its theoretically sound.
  
Another nice thing about the parallel index is that the idf relevancy factor stays clean since
it will only consider "real" documents.

I want to investigate these options closer ASAP since this feature you've implemented is something
I need.  Before I saw this issue, I was going to try something with SpanNearQuery and the
masking-field variant.
