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