• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (((lieu tinh) OR (bien tinh)))) - thanh trung cua dang cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (((lieu tinh) OR (bien tinh)))) - thanh trung cua dang cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (((lieu tinh) OR (bien tinh)))) - thanh trung cua dang cong san toan cau*.
