Subject [jira] [Commented] (SOLR-1726) Deep Paging and Large Results Improvements
Date Thu, 01 Dec 2011 03:27:41 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13160620#comment-13160620

-------------------------------------------------------

Hi Grant, thanks for your comments. Regarding the collectedHits, if there are 4 docs as results
and if we want to return only bottom 2 by giving appropriate pageScore and pageDoc, the expected
result is to return only 2 docs as results. But totalHits returns all the 4 docs. Thats the
reason i used collectedHits.
Kindly correct me if my understanding is wrong.

> There are possibly ways to improve collections of "deep paging" by passing Solr/Lucene
more information about the last page of results seen, thereby saving priority queue operations.
  See LUCENE-2215.
> There may also be better options for retrieving large numbers of rows at a time that
are worth exploring.  LUCENE-2127.
