• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - tranh trong chua dang huong ((dan toan) OR (((dan than) OR (dan chan)))) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - tranh trong chua dang huong ((dan toan) or (((dan than) OR (dan chan)))) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - tranh trong chua dang huong ((dan toan) or (((dan than) OR (dan chan)))) ban*.
