• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thieu nang ro hoi. hieu van thanh xuan va ((hanh vai) OR (hanh tai)) cau tren~.
• Adding a wildcard symbol may retrieve word variants: te sach thieu nang ro hoi. hieu van thanh xuan va ((hanh vai) or (hanh tai)) cau tren*.
