• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (toc thieu)) xanh - hanh tranh cua dong ((cong manh) OR (duong manh)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (toc thieu)) xanh - hanh tranh cua dong ((cong manh) OR (duong manh)) toan tap*".
