• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc hieu) OR (toc thieu)) cach - thanh ((trung cua) OR (trung cap)) dang luong giao thanh cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc hieu) or (toc thieu)) cach - thanh ((trung cua) OR (trung cap)) dang luong giao thanh cap*".
