Shawn Heisey commented on SOLR-12952:
-------------------------------------
Lucene scoring has always been influenced by deleted docs. SolrCloud's NRT
replica type has always had the potential for this problem, because different
replicas having different numbers of deleted documents has always been a
possibility. If you use TLOG/PULL replica types (new in 7.x) then all replicas
will be absolutely identical, and this can't happen.
It is not a bug. I don't know if eliminating the influence of deleted
documents on the scores in a query is even *possible*. Attempting to do it
would kill performance.

> Key: SOLR-12952
> URL: https://issues.apache.org/jira/browse/SOLR-12952
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: mosh
> Priority: Major
>
> I have recently noticed some odd behavior while using the edismax query
> parser.
> The scores returned by documents seem to be affected by deleted documents,
> which have yet to be merged and completely removed from the index.
> This causes different shards to return different scores for the same query.
> Is this a bug, or am I missing something?
