• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (theo tieu)) xanh - nhan khong tu hang dong ((san toan) OR (dan toan)) cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo tieu)) xanh - nhan khong tu hang dong ((san toan) OR (dan toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - nhan khong tu hang dong ((san toan) OR (dan toan)) cao".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) xanh - nhan khong tu hang dong ((san toan) OR (dan toan)) cao*.
