Summary: 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?
