Description

A few of us were discussing at Buzzwords on how a common use case requirement is "match documents which have values for a field"

To do this we need to query "-fq:brand:*" . This query can be slow and can be optimized

We can take advantage of NormsFieldExistsQuery and DocValuesFieldExistsQuery to speed up this use-case and not have to resort to WildcardQuery 

Today Solr's schema has doc-values enabled for fields that support it and for text fields norms are enabled by default so most users would already have the necessary indexed structures
