• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((hoang manh) OR (hoang minh)) cua dung phuong dan ((than tap) OR (han tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((hoang manh) or (hoang minh)) cua dung phuong dan ((than tap) OR (han tap))*".
