• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky ((lang xa) or (dang xay)) hoi. lieu va cam luc va doanh tai ((cuc te) OR (cuc thue))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky ((lang xa) OR (dang xay)) hoi. lieu va cam luc va doanh tai ((cuc te) OR (cuc thue)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky ((lang xa) or (dang xay)) hoi. lieu va cam luc va doanh tai ((cuc te) OR (cuc thue))".
• Adding a wildcard symbol may retrieve word variants: te sai ky ((lang xa) or (dang xay)) hoi. lieu va cam luc va doanh tai ((cuc te) OR (cuc thue))*.
