• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - hanh trang ((vat dung) OR (va dung)) trong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - hanh trang ((vat dung) OR (va dung)) trong dan toan ban".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) xanh - hanh trang ((vat dung) OR (va dung)) trong dan toan ban*.
