> Facet search on a docvalue field in a multi shard collection
> ------------------------------------------------------------
>
> Key: SOLR-5260
> URL: https://issues.apache.org/jira/browse/SOLR-5260
> Project: Solr
> Issue Type: Bug
> Components: search, SolrCloud
> Affects Versions: 4.4
> Reporter: Trym Møller
> Assignee: Erick Erickson
>
> I have a problem doing facet search on a doc value field in a multi shard collection.
> My Solr schema specifies fieldA as a docvalue type and I have created a two shard collection using Solr 4.4.0 (and the unreleased 4.5 branch).
> When I do a facet search on fieldA with a "large" facet.limit then the query fails with the below exception
> A "large" facet.limit seems to be when (10 + (facet.limit * 1,5)) * number of shards > rows matching my query
> The exception does not occur when I run with a single shard collection.
> It can easily be reproduced by indexing a single row and querying it, as the default facet.limit is 100.
> The facet query received by Solr looks as follows:
> {noformat}
> 576793 [qtp170860084-18] INFO org.apache.solr.core.SolrCore ¦ [trym_shard2_replica1] webapp=/solr path=/select

> One of the "internal query" send by Solr to its shard looks like
