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