[jira] Closed: (LUCENE-990) ParallelMultiSearcher.search with a custom HitCollector should run parallel

["Uwe Schindler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-990?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Uwe Schindler closed LUCENE-990.
--------------------------------

    Resolution: Won't Fix

ParallelMultiSearcher was dropped with MultiSearcher in Lucene trunk (because of too mayn unsolveable scoring and deMorgan bugs). The replacement is a parallelized IndexSearcher on MultiReaders.

It's not possible to solve this even for the new one, as it would need Collector to be synchronized.

> The ParallelMultiSearcher.search(Weight weight, Filter filter, final HitCollector results) should search over its underlying Searchers in parallel, like the TopDocs versions of the search() method. There's a @todo for this in the method's Javadoc comment.
