indexing SET columns

Hello,

I was doing some testing, and had a multi-column index created for a bunch of columns called "test1", and then i creaetd an indentical index called "test2" except it i took out the SET column. when i did an EXPLAIN SELECT query, it picked the "test2" index, when one of the WHERE conditions was (FIND_IN_SET("1", set_column)>0).

Is there a way to create the index on the table or is there a certain way to structure the SELECT query to use the index of the set_column?
