[jira] [Updated] (LUCENE-4858) Early termination with
SortingMergePolicy
[ https://issues.apache.org/jira/browse/LUCENE-4858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shai Erera updated LUCENE-4858:
-------------------------------
Attachment: LUCENE-4858.patch
Patch adds Sorter.getID() and the collector to check whether the given Sorter matches the one that's recorded in the segment. I added a test to TestEarlyTermination which fails if the added check to sorted() is removed.
