Deepika Sharma commented on LUCENE-10544:
-----------------------------------------
For adding timeout feature In {{IndexSearcher}} through {{BulkScorer}}
approach, I think there are two ways we can implement this:
* One way could be we can make another class which will wrap {{BulkScorer}}
along with timeout and other methods as per required (similar to existing
{{TimeLimitingCollector}} class).
* Another way could be making a helper function inside {{BulkScorer}} class
which will wrap score method of {{BulkScorer}} along with timeout and it will
invoke whenever timeout is enabled.
So, I am looking for the suggestion which approach would be better to go ahead
or is there any other way I should consider?

> Key: LUCENE-10544
> URL: https://issues.apache.org/jira/browse/LUCENE-10544
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/index
> Reporter: Greg Miller
> Priority: Major
>
> While looking into options for LUCENE-10151, I noticed that
> {{ExitableDirectoryReader}} doesn't actually do any timeout checking once you
> start iterating postings/impacts. It *does* create a {{ExitableTermsEnum}}
> wrapper when loading a {{{}TermsEnum{}}}, but that wrapper doesn't do
> anything to wrap postings or impacts. So timeouts will be enforced when
> moving to the "next" term, but not when iterating the postings/impacts
> associated with a term.
> I think we ought to wrap the postings/impacts as well with some form of
> timeout checking so timeouts can be enforced on long-running queries. I'm not
> sure why this wasn't done originally (back in 2014), but it was questioned
> back in 2020 on the original Jira SOLR-5986. Does anyone know of a good
> reason why we shouldn't enforce timeouts in this way?
> Related, we may also want to wrap things like {{seekExact}} and {{seekCeil}}
> given that only {{next}} is being wrapped currently.
