Hello 
I have magento 2.3 cummunity edition and i configured elasticsearch 5.2 as a search engine for magento, the default index is named: catalogsearch_full text BUT i don't want to use it !! because i made the indexing through a talend job and i launch it with a job i created in magento, and i created a new index through talend , i want that magento now uses the index i created rather then the one by default(catalogsearch_fulltext) so that search results will be rendered through my new index, how can i do that ???
I NEED A QUICK RESPONSE PLEASE :'(
