which is at this area of the code in the aggregator, but not the root cause...

FacetInfo fi = rb._facetInfo;

// int shardNum = rb.getShardNum(srsp.shard);

The shard actually has an error on it, which is:

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.
