• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang xa hoi. hieu v pham duc ban ((thanh hai) OR (thanh hoa)) ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang xa hoi. hieu v pham duc ban ((thanh hai) or (thanh hoa)) ((cua tre) OR (cua triet))".
