Hi Toke The number of collection is just 10.One of collection has 43 shards,each shard has two replicas.We continue importing data from oracle all the time while our systems provide searching service. There are "Overlapping onDeckSearchers" in my solr.logs. What is the meaning about the "Overlapping onDeckSearchers" ,We set the the < maxWarmingSearchers>20</maxWarmingSearchers> and <useColdSearcher>true</ useColdSearcher>.Is it right ?
