Adrien Grand commented on LUCENE-8101:
--------------------------------------
Is it a dup of LUCENE-7714?
> Make NumericDocValuesField.newSlowExact/RangeQuery fast with a sorted index
> ---------------------------------------------------------------------------
>
> Key: LUCENE-8101
> URL: https://issues.apache.org/jira/browse/LUCENE-8101
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Michael McCandless
>
> 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?
