• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((trieu dinh) OR (hieu lang)) - hanh trinh cua dang cong ((van toan) OR (van tuan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((trieu dinh) or (hieu lang)) - hanh trinh cua dang cong ((van toan) OR (van tuan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((trieu dinh) or (hieu lang)) - hanh trinh cua dang cong ((van toan) OR (van tuan)) cao*.
