Hi, I would like to have more understanding of the lifecycle for IndexSearcher in Solr, I understand that IndexSearcher for Lucene would recommended that “For performance reasons, if your index is unchanging, you should share a single IndexSearcher instance across multiple searches instead of creating a new one per-search.” (based on Lucene 4.6.1 version<https://lucene.apache.org/core/4_6_1/core/org/apache/lucene/search/IndexSearcher.html>).
But when things come to Solr world which in a Java Webapp with servlet dispatcher. Do we also keep reusing the same IndexSearcher instance as long as there is no index changing? I see “Hossman” had this talk for the lifecycle of the solr search request<https://home.apache.org/~hossman/rev2017/>, but he doesn’t mention anything about how we handle/cleanup the indexsearcher. Thanks, Xiaolong
