• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((nang ma) OR (sang ma)) hoi. hieu ((he nam) OR (nghe nam)) thu dia danh sai cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang ma) or (sang ma)) hoi. hieu ((he nam) or (nghe nam)) thu dia danh sai cuu tre*.
