That's not what MUL means. MUL means that the index is not unique --
i.e., you can have several rows with the same indexed column values.
For example, a primary key column (usually an ID) is unique. But if you
have a database of employees and you want to index them by first name,
you would not use a unique index on the "first_name" column.
