Alessandro Benedetti commented on SOLR-7190:
--------------------------------------------

According to Shalin comment, what will happen now if a request has the 
facet.method=fc and we don't have docValues for the field of interest for 
faceting calculations ?

Have I confused the message ? DocValues should not be mandatory right ?
Is now another way to access the algorithm without docValues ?

> Remove unused UninvertedField

> I was surprised to find that UninvertedField is no longer used in Solr. The 
> only references to UninvertedField is from the fieldValueCache inside 
> SolrIndexSearcher and that itself is not used anywhere in SolrIndexSearcher 
> except for initialization and regeneration. I can't trace when Solr stopped 
> using this class but in any case, we should remove it.
> In a related note, Lucene's DocTermOrds has a copy of the class level 
> javadocs of UninvertedField (which extends DocTermOrds). This was done in in 
> LUCENE-5666.
