[jira] [Commented] (LUCENE-8808) Introduce Optional Cap on Number
Of Threads Per Query
[ https://issues.apache.org/jira/browse/LUCENE-8808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16845796#comment-16845796 ]

[~jpountz] Does this seem like a useful thing?

> Key: LUCENE-8808
> URL: https://issues.apache.org/jira/browse/LUCENE-8808
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Reporter: Atri Sharma
> Priority: Major
>
> With the presence of https://issues.apache.org/jira/browse/LUCENE-8757 , a natural progression is to allow advanced users to specify a cap on the number of threads a query can use. This is especially useful for long polled IndexSearcher instances, where the same instance is used to fire queries for multiple runs and there are multiple concurrent IndexSearcher instances on the same node.
>
> This will be an optional parameter and local only to the IndexSearcher instance being configured during construction.
