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