The UninvertedField has internal limits that makes it impossible to use for un-inverting String fields with many referenced. That is one of the reasons for using DocValues for faceting in the first place.
Using indexed String values as source for conversion to DocValues requires an UnInverter with higher limits than the one standard Solr has.
