Description

SolrIndexSearcher is nearly 3 thousand lines of code. A sizable part of it pertains to Document handling, including various stored-field concerns and docValue substitutions (docValueAsStored related). There are already comments marking the start and end of this part of SolrIndexSearcher, plus there some fields and their initialization that are only in support of those methods. I propose that all of this go to a new companion class SolrDocumentFetcher. SolrIndexSearcher can add a getter for it, and where applicable existing callers can call to this instead. "Override"'s will need to stay of course.
