As I understand it, this only applies to Solr startup or core reload, because that's the only time you'd normally have no registered searchers. The warming queries in that case are defined by firstSearcher and newSearcher events, they aren't your cache autowarming. For cache autowarming, you have a registered searcher already. Now I will answer a question that you asked on IRC early this morning (in my timezone): If you are seeing messages in your log about exceeding maxWarmingSearchers, then it is likely that the amount of time that it takes for warming is exceeding the amount of time before the next commit comes in. Thanks, Shawn
