• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - nhanh ((huong va) OR (luong va)) nhung cong tac ((chan cau) OR (chinh cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - nhanh ((huong va) OR (luong va)) nhung cong tac ((chan cau) or (chinh cau))".
