I installed Enhanced search. When rebuild index, should I before that delete old index ? If answer is yes, where to do that? With option in Tools=>ElasticSearch setup or in Tools=> Rebuild caches => Rebuild Search Index =>Delete the index before rebuilding For option Elasticsearch Index Name, should be allways the same even if I going to rebuild search index or I have to change before every rebuild? Option Search Minimum Word Length is for mysql only? Should I change that to 2 or 3 or by default no matter what number is set there, I can search even 2 letters with Enhanced search installed and enabled? Or somewhere I have to setup minimum letters for enhanced search?
