• If you are trying to use Boolean operators, they must be ALL CAPS: toc thi thanh - ((hanh trinh) OR (canh tranh)) cua hang cong ban ((thanh nha) OR (thanh ha))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thi thanh - ((hanh trinh) or (canh tranh)) cua hang cong ban ((thanh nha) OR (thanh ha))~".
• Adding a wildcard symbol may retrieve word variants: toc thi thanh - ((hanh trinh) or (canh tranh)) cua hang cong ban ((thanh nha) OR (thanh ha))*.
