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