---------------------------------
Attachment: LUCENE-7461.patch
Here is a patch that implements this idea.
> 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
> Attachments: LUCENE-7461.patch
>
>
> 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.
