• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((anh tang) OR (anh dung)) ((cua hang) OR (cua dang)) cong san toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((anh tang) or (anh dung)) ((cua hang) or (cua dang)) cong san toan cau*.
