Как исключить не полные повторения строк?

SELECT
	SIGN(COALESCE(location_id, 0)) + SIGN(COALESCE(division_id, 0)) + SIGN(COALESCE(position_id, 0)) as score, 
    keyword.*
FROM
	keyword
WHERE 
	(city_id = 5 OR city_id IS NULL) AND
    (location_id = 7 OR location_id IS NULL) AND
    division_id IS NULL AND
    position_id IS NULL AND
    MATCH (keyword) AGAINST ('еда банкомат') 
GROUP BY
	title
DESC
ORDER BY
	score
DESC
LIMIT 10
