Subject [jira] Updated: (LUCENE-1539) Improve Benchmark
Date Wed, 08 Apr 2009 21:26:13 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-1539?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Rutherglen updated LUCENE-1539:
-------------------------------------

    Attachment: LUCENE-1539.patch

Above mentioned issues fixed.

It seems a bit awkward that DeleteByPercentTask needs to call
IR.undeleteAll before executing the deletes. Also that
subsequent delete by percent calls in deletepercent.alg need to
open the latest version of the index rather than the original
(which does not have deletes). This is due to
DirectoryIndexReader.acquireWriteLock checking to insure the
latest version of the index is locked. Perhaps we can relax
this? I would rather be able to open a commit point and delete
from the reader, then flush as the latest version.

Perhaps in flexible indexing we can have more customizability
with the versioning?
