• If you are trying to use Boolean operators, they must be ALL CAPS: ((cot lieu) OR (co lieu)) tinh - hanh manh ((cua dang) OR (cua ban)) hung manh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((cot lieu) or (co lieu)) tinh - hanh manh ((cua dang) OR (cua ban)) hung manh toan tap".
• Adding a wildcard symbol may retrieve word variants: ((cot lieu) or (co lieu)) tinh - hanh manh ((cua dang) OR (cua ban)) hung manh toan tap*.
