The IN operator allows you to determine if a specified value matches any value in a set of values or returned by a subquery. The following illustrates the syntax of the IN operator: SELECT column1,column2, FROM table_name WHERE (expr|column_1) IN ('value1', 'value2',);
Elastic search full text vs mysql full text?, With MySQL you will always be indexing and searching your data. With ElasticSearch you have more flexibility in what you index as one unit. While MySQL is database management system itself, ElasticSearch is only a search engine. The data on which search is performed is stored in it's index (ElasticSearch data store is called index). This index sometimes likes to fail, and then you need to have your data backuped in some external database (I'm using NoSQL solution - MongoDB, as I struggle with BigData problem), from which you restore it.
