• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat sach)) ky nang x hoi. hieu ve cam xuc va hanh ((vi cua) OR (di cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat sach)) ky nang x hoi. hieu ve cam xuc va hanh ((vi cua) OR (di cua)) te".
