Subject [jira] [Commented] (LUCENE-2454) Nested Document query support
Date Tue, 21 Jun 2011 16:35:48 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13052648#comment-13052648
] 

Michael McCandless commented on LUCENE-2454:
--------------------------------------------

bq. A common pattern is for solutions to ask for the best 11 children for the best parents
and display only 10 - that way the app knows that for certain parents there is more data available
(i.e. those with 11 matches) and can offer a "more" button to retrieve the extra children
for parents of interest

With LUCENE-3171, you should be able to just ask for 10 here, and then check if the TopDocs.totalHits
is > 10 to decide whether to offer the "more" button.
