   > We need two cases:
   > 
   > * Checking whether all documents match and returning values.getDocCount(). This works when there are no deletions.
   > * Actually counting the number of matching points. This only works when there are no deletions and the field is single-valued (docCount == size), plus we only want to apply it in the 1D case since this is the only case when we have the guarantee that it will actually run fast since there are at most 2 crossing leaves.
