• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((hieu manh) OR (chieu xanh))) OR (thien anh)) - tranh trong su dung cong thanh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((hieu manh) OR (chieu xanh))) or (thien anh)) - tranh trong su dung cong thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((hieu manh) OR (chieu xanh))) or (thien anh)) - tranh trong su dung cong thanh toan tap*.
