Ishan Chattopadhyaya commented on SOLR-13350:
---------------------------------------------

bq. Do we have a limited queue for the pool, leading to the 
"RejectedExecution"?  I think we'd like a caller-runs policy so we don't wait & 
starve

Changed it to a larger queue than then number of threads, and removed the 
rejected execution handler as well.

bq. Commit ff6607d25f023a59f866a66820037bb215342ca8 in solr's branch 
refs/heads/main from Ishan Chattopadhyaya
Will backport to branch_9x after a few days of baking on main.

> 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.
