> Other related information:
> * The facet being selected is a multi-valued field
> * The facet is a dynamic field and passes a dynamic rule
> * The facet exists and the log shows the 2nd follow-on querying asking for shard values
> * When running a query for a single valued field it seems to work fine, only multi-valued fields seem to fail. Not completely verified, but a few tests hint at this.
> * Tried facet names that were simple such as "ISBN" and if multi-valued, produces same error.
> * Tried facet names with underscores to see if that was at issue, and if single valued, it succeeded.
> * In a non-distributed search, the tag/exclude works fine for the same facets.
