Enable range keys in batch count queries
Enable range keys in batch count queries

Enable keys to count using range keys such as "gte" (greater or equal
than) or "lt" (less than) when doing batch count queries.  This is
useful in particular to count the documents with a number of errors or
warnings greather than 0 (gte 1).
