I have seen this question everywhere but the answer is just explaining some technical stuff without a clear verdict so I have to make my question so narrow that no one mistakes it with another question:
I have a table with millions of records. This table has a string field and I need to search it normally and full-text. So of course I need it to be fulltext but does it make it faster for my normal search if I add "index" as well?
Another word: Does full-text cover simple index?
