In the javadocs for {{IndexSearcher.search}} I think you mean "In contrast to"
instead of "On the contrary to"?

> IndexSearcher takes an ExecutorService that can be used to parallelize
> collection execution. This is useful if you want to trade throughput for
> latency.
> However, this executor service will only be used if you search for top docs.
> In that case, we will create one collector per slide and call TopDocs.merge
> in the end. If you use search(Query, Collector), the executor service will
> never be used.
> But there are other collectors that could work the same way as top docs
> collectors, eg. TotalHitCountCollector. And maybe also some of our users'
> collectors. So maybe IndexSearcher could expose a generic way to take
> advantage of the executor service?
