> Remove the "estimate match count" optimization from point queries

> Key: LUCENE-7051
> URL: https://issues.apache.org/jira/browse/LUCENE-7051
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand

> Priority: Minor
> Attachments: LUCENE-7051.patch
>
>
> Point queries try to estimate the number of matches in the visitor so that
> the doc id set that they build does not have to do it by itself. However,
> this is incorrect in the multi-valued case and does not seem to buy much (if
> any) in terms of performance?
