Subject [jira] Updated: (LUCENE-2597) Query scorers should not use MultiFields
Date Wed, 11 Aug 2010 16:01:24 GMT


Michael McCandless updated LUCENE-2597:

    Attachment: LUCENE-2597.patch

Attached patch.

Only a few query impls were affected, but many tests were directly passing composite readers
to the low level API.  I added a new helper class SlowMultiReaderWrapper that one can use
to wrap an existing composite reader to make it [inefficiently] pretend it's an atomic reader.

> Lucene does all searching/filtering per-segment, today, but there are a number of tests
that directly invoke Scorer.scorer or Filter.getDocIdSet on a composite reader.
