• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sach) OR (thu hoach)) ky tang van hoc. thien van ((nam xuc) OR (cam xuc)) va danh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (thu hoach)) ky tang van hoc. thien van ((nam xuc) OR (cam xuc)) va danh vai cua te".
