• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu tinh) OR (trieu tinh)) - hanh ((trang cua) OR (hang cua)) dung cong manh toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (trieu tinh)) - hanh ((trang cua) or (hang cua)) dung cong manh toan cao*".
