Shalin Shekhar Mangar commented on SOLR-1030:
---------------------------------------------
Another point, consistency is not guaranteed between query phases in the
current implementation. So if a commit happens on a shard in between a query
phase and facet refinement phase, you may see different counts.
> Facet counts are not correct (or total document count is not correct as they
> do not match) on some searches

> Key: SOLR-1030
> URL: https://issues.apache.org/jira/browse/SOLR-1030
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 1.4
> Reporter: Jayson Minard
>
> There isn't much detailed evidence for this one yet, but hopefully it rings a
> bell with someone who made changes in this area recently...
> Since updating to the tip from our previous use of the tip from around Jan 9,
> 2009 we are now seeing facet counts no longer match total document count.
> This is through distributed search and I have not verified that it only
> happens on distributed vs. single shard search so it could be on both.
> For example, on a single valued field with one facet value set as a fq
> filter, combined with a text search on a simple term "science", the following
> is the facet count:
> 8,294,284
> And the total document count for the same results is:
> 8,294,274
> some debug info (not sure why the filter query is replicated more than once,
> but that shouldn't be harmful):
> {code}
> uerystring (science)
> QParser OldLuceneQParser
> filter_queries [sys_content_type:("Journal Article"),
> sys_content_type:("Journal Article"),
> sys_content_type:("Journal Article"), sys_content_type:("Journal Article"),
> sys_content_type:("Journal Article"), sys_content_type:("Journal Article"),
> sys_content_type:("Journal Article"), sys_content_type:("Journal Article"),
> sys_content_type:("Journal Article"), sys_content_type:("Journal Article")]
> rawquerystring (science)
> {code}
