> If I sort my index by a doc values field A, then run a query like {{NumericDocValuesField.newSlowExactQuery(A,
10)}}, it should somehow be possible to run that query efficiently, i.e. it will be a compact
range of doc ids that match.
> The challenge is, without an inverted structure, how will we know exactly which range
of docIDs?  If the field is also indexed e.g. as points, we could use that to locate the min/max
docID, maybe?
