• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (tieng anh)) - hang ban qua duong cong dan ((toan cau) OR (toan cao)).
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) or (tieng anh)) - hang ban qua duong cong dan ((toan cau) or (toan cao))*.
