    Description

      For geo queries on small and dense datasets with small limits, the initial coverings are often too large. This can result in fetching many more documents than necessary to satisfy the query. This is the cause of the issue described in SERVER-18724.

      To remedy this, we should increase the finest possible query region covering. This includes both the annuluses used in geo near queries and any region supplied to in an intersects or within query.
