• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sai) OR (tu cai))) OR (te bai)) ky dang ngoai hoi. hieu vu cham quoc quan sang vi cua te~.
• Adding a wildcard symbol may retrieve word variants: ((((tu sai) or (tu cai))) or (te bai)) ky dang ngoai hoi. hieu vu cham quoc quan sang vi cua te*.
