DISTINCT i full text

Jeg er ved at lave et site med full text søgning, men vil gerne have en DISTINCT på den .. er det muligt ?

min sql er som det her ;
SELECT MATCH (test1,test2) AGAINST ('+hvad' IN BOOLEAN MODE) as score, test1, test2, Base, test3 FROM w WHERE MATCH (test1,test2) AGAINST ('+hvad' IN BOOLEAN MODE) order by score desc LIMIT 0,20

Men synes ikke virker
SELECT DISTINCT (Base), MATCH (test1,test2) AGAINST ('+hvad' IN BOOLEAN MODE) as score, test1, test2, test3 FROM w WHERE MATCH (test1,test2) AGAINST ('+hvad' IN BOOLEAN MODE) order by score desc LIMIT 0,20
