• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (chieu sang)) - thanh truong va thanh cong ((dan toan) OR (manh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sang)) - thanh truong va thanh cong ((dan toan) OR (manh toan)) cau*".
