• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (chieu xanh)) - ((hanh trang) OR (thanh trung)) cua thong thong hach toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (chieu xanh)) - ((hanh trang) OR (thanh trung)) cua thong thong hach toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (chieu xanh)) - ((hanh trang) OR (thanh trung)) cua thong thong hach toan tap*.
