--------------------------------------------------

  == Stray bits ==
  
  Memory consumption per filter field value is not a great concern here
- as the `filterCache` typically (perhaps always) stores only bit vectors,
+ as the `filterCache` stores relatively compact representations such as bit vectors 
+ (or smaller representations, depending on the set cardinality) with
  each bit representing a boolean to signal whether or not the document in question
  is a member of the set matching the filter specification.
  Document reference is implicit by each bit's position in the vector;
