• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((hoi nang) OR (ho nang)) x ho. hieu ve cam xuc ((ban hanh) OR (va dinh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((hoi nang) OR (ho nang)) x ho. hieu ve cam xuc ((ban hanh) or (va dinh)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ((hoi nang) OR (ho nang)) x ho. hieu ve cam xuc ((ban hanh) or (va dinh)) vi cua te*.
