• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu bang - ((hanh trang) OR (canh tranh)) cua nhung cong tan ((tran cau) OR (ran cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu bang - ((hanh trang) OR (canh tranh)) cua nhung cong tan ((tran cau) or (ran cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chu bang - ((hanh trang) OR (canh tranh)) cua nhung cong tan ((tran cau) or (ran cau))*.
