Subject [jira] [Updated] (SOLR-2950) QueryElevationComponent needlessly looks up document ids
Date Wed, 14 Dec 2011 12:53:30 GMT


Grant Ingersoll updated SOLR-2950:

    Attachment: SOLR-2950.patch

First draft.  This just does the mapping in the constructor to the comparator.  We could do
setNextReader, but I can't imagine it will really make much difference given the small number
of items that we typically would expect to be elevated.

> 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.
