• If you are trying to use Boolean operators, they must be ALL CAPS: nho ((hieu lang) OR (nhieu tang)) - anh dang duc ((cong cong) OR (dung cong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nho ((hieu lang) OR (nhieu tang)) - anh dang duc ((cong cong) or (dung cong)) dan than cau".
