• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu tinh - ((hanh trang) OR (canh tranh)) ((cua cong) or (cua nhung)) cong dan phan lap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tinh - ((hanh trang) OR (canh tranh)) ((cua cong) OR (cua nhung)) cong dan phan lap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tinh - ((hanh trang) OR (canh tranh)) ((cua cong) or (cua nhung)) cong dan phan lap".
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - ((hanh trang) OR (canh tranh)) ((cua cong) or (cua nhung)) cong dan phan lap*.
