• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (chieu sach))) OR (thieu quang)) - hanh trung cua hang cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) or (chieu sach))) or (thieu quang)) - hanh trung cua hang cong dan toan cau*.
