• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thien danh) OR (hieu manh)) - thanh ((trung va) OR (trang va)) nhung cong van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thien danh) or (hieu manh)) - thanh ((trung va) OR (trang va)) nhung cong van toan cao".
• Adding a wildcard symbol may retrieve word variants: toc ((thien danh) or (hieu manh)) - thanh ((trung va) OR (trang va)) nhung cong van toan cao*.
