How to clear this cache?
I don't think there is any way to do EXACTLY what you are asking. If you reload the collection (or each of its cores), then the cache will be cleared and re-created, and will only contain data queried by the firstSearcher event listener. If you edit the configuration linked to that collection (or link another suitable config, assuming SolrCloud) to remove the cache configurations and the event listeners, then there will be no cache when you reload it.
