Gus Heck commented on SOLR-13350:
---------------------------------
I seem to recall seeing discussion of making this feature experimental and off
by default due to unclear performance gains, but none of the commit messages I
see here indicate that that has happened yet?

> AFAICT, SolrIndexSearcher can be used only to search all the segments of an
> index in series. However, using CollectorManagers, segments can be searched
> concurrently and result in reduced latency. Opening this issue to explore the
> effectiveness of using CollectorManagers in SolrIndexSearcher from latency
> and throughput perspective.
