• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - hanh tinh cua dang cong manh ((toan ban) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - hanh tinh cua dang cong manh ((toan ban) or (toan cao))*.
