Subject [jira] [Updated] (LUCENE-2919) IndexSplitter that divides by primary key term
Date Sat, 18 Jun 2011 08:28:47 GMT


Uwe Schindler updated LUCENE-2919:

    Attachment: LUCENE-2919-filter.patch

New patch:
- simplified the Filter logic
- added option to negate the filter in the IndexReader, this enabled use of only *one* TermRangeFilter
and simply negate it for the second pass.
- made code correctly close using IOUtils.closeSafely

Tests are still ugly.

> Index splitter that divides by primary key term.  The contrib MultiPassIndexSplitter
we have divides by docid, however to guarantee external constraints it's sometimes necessary
to split by a primary key term id.  I think this implementation is a fairly trivial change.
