• If you are trying to use Boolean operators, they must be ALL CAPS: he ((nhieu tang) OR (nhiet nang)) - thanh tran tuan dung ((cong tan) OR (cong san)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "he ((nhieu tang) or (nhiet nang)) - thanh tran tuan dung ((cong tan) OR (cong san)) toan cau*".
