Adrien Grand resolved LUCENE-8905.
----------------------------------
Fix Version/s: master (9.0)
Resolution: Fixed
> TopDocsCollector Should Have Better Error Handling For Illegal Arguments
> ------------------------------------------------------------------------
>
> Key: LUCENE-8905
> URL: https://issues.apache.org/jira/browse/LUCENE-8905
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Atri Sharma
> Priority: Major
> Fix For: master (9.0)
>
> Time Spent: 7h 10m
> Remaining Estimate: 0h
>
> While writing some tests, I realised that TopDocsCollector does not behave
> well when illegal arguments are passed in (for eg, requesting more hits than
> the number of hits collected). Instead, we return a TopDocs instance with 0
> hits.
>
> This can be problematic when queries are being formed by applications. This
> can hide bugs where malformed queries return no hits and that is surfaced
> upstream to client applications.
>
> I found a TODO at the relevant code space, so I believe it is time to fix the
> problem and throw an IllegalArgumentsException.
