• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((cach dung) OR (tac dung)) luan hung ((cuong thanh) OR (cong thanh)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((cach dung) or (tac dung)) luan hung ((cuong thanh) OR (cong thanh)) toan cau*".
