    Description

      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.
