------------------------------------
Summary: Speed up point ranges that match most documents
Key: LUCENE-7641
URL: https://issues.apache.org/jira/browse/LUCENE-7641
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
If a point range matches most documents and every document has exactly one
value, then we could make things faster by computing the set of documents that
do NOT match the range instead.
It was not possible until recently since figuring out whether a range query
matches most documents was not possible, but we can now use the new
{{ScorerSupplier.cost}} API to do that: we could just check whether the cost of
the inverse visitor is lower than the cost of the regular range visitor.
