[jira] [Commented] (LUCENE-4752) Merge segments to sort them

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/LUCENE-4752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13607647#comment-13607647 ]

Adrien Grand commented on LUCENE-4752:

I opened LUCENE-4858 to deal with early query termination (as you suggested earlier) so that we can concentrate on sorting in this issue.

bq. Adrien, perhaps in order to keep the patch small, commit separately the changes to LTC and TestDuelingCodec (as well as the SortingAtomicReader.wrap change)

I'll do that soon if nobody objects.

> It would be awesome if Lucene could write the documents out in a segment based on a configurable order.  This of course applies to merging segments to. The benefit is increased locality on disk of documents that are likely to be accessed together.  This often applies to documents near each other in time, but also spatially.
