• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sanh)) y nang xa hoi. hieu va bac thuc va dan vi ((cuu tre) OR (cau tren))~.
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (so sanh)) y nang xa hoi. hieu va bac thuc va dan vi ((cuu tre) or (cau tren))*.
