• If you are trying to use Boolean operators, they must be ALL CAPS: ((chao chu) OR (cho chu)) bang - anh bang ((cua thong) OR (cua khong)) tong minh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((chao chu) or (cho chu)) bang - anh bang ((cua thong) or (cua khong)) tong minh toan cau*.
