mysql FULLTEXT search multiple words

I've never really heard a straight answer on this one, I just need to FULLTEXT search a couple columns with multiple words "Firstname Lastname"

$sql = mysql_query("SELECT * FROM 
                    patient_db 
                    WHERE MATCH ( Name, id_number )
                    AGAINST ('% $term %' IN BOOLEAN MODE);");

But it fails to run the query if I enter more than one word here.
