• If you are trying to use Boolean operators, they must be ALL CAPS: doc chieu xanh - ((((anh quan) OR (anh nhan))) OR (anh dung)) va thong cong dan than ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc chieu xanh - ((((anh quan) OR (anh nhan))) or (anh dung)) va thong cong dan than ban*".
