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