• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky dong ha noi. hieu ((van cham) OR (van tham)) ((duc ban) OR (duc van)) hanh va cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky dong ha noi. hieu ((van cham) OR (van tham)) ((duc ban) or (duc van)) hanh va cua tuc*".
