Subject [jira] Commented: (LUCENE-2007) Add DocsetQuery to turn a DocIdSet into a query
Date Sat, 24 Oct 2009 15:19:59 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2007?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12769667#action_12769667
] 

Uwe Schindler commented on LUCENE-2007:
---------------------------------------

It is exactly the same like ConstantScoreQuery, the only difference is that it gets an DocIdSet
as parameter. My problem with it: How should this work with Multi-Segment indexes (because
search is done on each segment) and once the iterator is exhausted it cannot be used anymore
and how does the query know, for which segment the query applies?
