> Code cleanup - Avoid using stream filter count where possible

> Key: SOLR-13542
> URL: https://issues.apache.org/jira/browse/SOLR-13542
> Project: Solr
> Issue Type: Improvement
> Components: SolrJ
> Reporter: Koen De Groote
> Priority: Trivial
> Time Spent: 40m
> Remaining Estimate: 0h
>
> This is another ticket in the logic of
> https://issues.apache.org/jira/browse/LUCENE-8847
>
> Not a feature, not serious, don't review this when you could be reviewing
> actual features or critical bugs, don't want to take your time away with this.
>
> Intellij's static code analysis bumped into this.
>
> I also saw most other instances in the code where such a filter needed to
> happen already used
> {code:java}
> anyMatch{code}
> instead of count(). So I applied the suggested fixes. Code cleanup and
> potentially a small performance gain. As far as my understanding goes, since
> it is not a simple count that's happening, there's no known size for the
> evaluator to return and as such it has to iterate over the entire collection.
> Whereas anyMatch and noneMatch will use the predicate to stop the instance
> the condition is met.
> It just so happens that all affected instances exist within the SolrJ
> namespace.
>
> All tests have run, all succeed.
