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