title: MySQL: Index for two boolean fields
body: <p>I have a MySQL table with two boolean (TINYINT or BIT or something like this) fields.</p>
  
  <p>For efficient counting (and paginating in general, just is for "cutting" a slice from the DB to show in a page of a pagination) all rows where both booleans are false, should I create an index on each of these two fields, composite index on both fields, or both?</p>
