• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky tang ma hoi. hieu van ((cham xuc) OR (cam xuc)) va hanh ((vi cua) OR (di cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky tang ma hoi. hieu van ((cham xuc) OR (cam xuc)) va hanh ((vi cua) or (di cua)) triet*".
