• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ky ((nang ma) OR (sang ma)) hoi. hieu ve cam xuc va ((danh sai) OR (dung dat)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ky ((nang ma) OR (sang ma)) hoi. hieu ve cam xuc va ((danh sai) or (dung dat)) cua te".
