Mysql Improve Search Performance with wildcards (%%)

Question

Below is a query I use for searching a person by email

  SELECT *
    FROM phppos_customers
    JOIN phppos_people ON phppos_customers.person_id = phppos_peo         


        

Answer 1

No, because MySQL will not be able to utilize the index when you have a leading wildcard. If you changed your LIKE to 'f%', then it would be able to use the index.
