• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ((((ky lang) OR (ky dang))) OR (ky nang)) xa hoi. hieu va hau loc va hanh vi su triet.
• Adding a wildcard symbol may retrieve word variants: te cac ((((ky lang) or (ky dang))) or (ky nang)) xa hoi. hieu va hau loc va hanh vi su triet*.
