• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ky tang) OR (ky nang)) ma hoa. hieu ((ve cham) OR (va cham)) luc van dinh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ky tang) OR (ky nang)) ma hoa. hieu ((ve cham) or (va cham)) luc van dinh vi cua te*".
