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