• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (hoc thieu)) xanh - hanh ((chinh taa) OR (chinh ta)) bang cong van tan cao~.
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (hoc thieu)) xanh - hanh ((chinh taa) or (chinh ta)) bang cong van tan cao*.
