• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky lang xa hoi. hieu van lam xuc ((va thanh) OR (va tinh)) ((vai cua) OR (tai cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky lang xa hoi. hieu van lam xuc ((va thanh) OR (va tinh)) ((vai cua) or (tai cuc)) tre".
