Thanks for the clarifications, Yonik. The other thing I notice is openSearcher() only creates a SolrIndexSearcher without cache (useCache = false). Therefore, when I try to use generic cache defined in solrconfig.xml, SolrIndexSearcher.getCache() method returns null. Would it be OK to turn on searcher cache?
