• Performing a fuzzy search may retrieve terms with similar spellings: ((mot chieu) or (theo tieu)) sang - khach ((san va) OR (san van)) nhung cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo tieu)) sang - khach ((san va) OR (san van)) nhung cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo tieu)) sang - khach ((san va) OR (san van)) nhung cong dan toan cao*".
