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