• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky lang mai hoi. hieu ve cam ((xuc ban) OR (((luc van) OR (duc van)))) hanh voi hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang mai hoi. hieu ve cam ((xuc ban) or (((luc van) OR (duc van)))) hanh voi hoa viet".
