• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((((hanh tang) OR (hanh tung))) OR (anh tang)) cua nhung chong van toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((((hanh tang) OR (hanh tung))) or (anh tang)) cua nhung chong van toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((((hanh tang) OR (hanh tung))) or (anh tang)) cua nhung chong van toan cao*.
