Yonik Seeley updated SOLR-2950:
-------------------------------
Attachment: SOLR-2950.patch
OK, just had a chance to view the comparator part of this patch.
Here's a patch that fixes
- minor check-for-null for fields() and terms() which can return null
- even though docsEnum returns something, it may be deleted (i.e. need to
check for NO_MORE_DOCS)
- use liveDocs when requesting the docsEnum so we won't use a deleted
(overwritten) doc.
The last two issues would both cause us to miss elevated documents if they have
been updated and an old deleted version still exists in the index.

> The QueryElevationComponent needlessly instantiates a FieldCache and does
> look ups in it for every document. If we flipped things around a bit and got
> Lucene internal doc ids on inform() we could then simply do a much smaller
> and faster lookup during the sort.
