• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. lieu va ((cam luc) OR (cau luc)) ((va hang) OR (va nang)) mai duc tre.
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. lieu va ((cam luc) or (cau luc)) ((va hang) or (va nang)) mai duc tre*.
