• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ((lai hoi) or (((dai hoa) OR (dai hoc)))). hieu ve cham xuc ban hang di cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((lai hoi) OR (((dai hoa) OR (dai hoc)))). hieu ve cham xuc ban hang di cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((lai hoi) or (((dai hoa) OR (dai hoc)))). hieu ve cham xuc ban hang di cua tu".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((lai hoi) or (((dai hoa) OR (dai hoc)))). hieu ve cham xuc ban hang di cua tu*.
