• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang ma hoi. hieu ve cam xuc ((va hanh) OR (van hanh)) vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sac ky)) nang ma hoi. hieu ve cam xuc ((va hanh) or (van hanh)) vi cuu tre*.
