• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((ky dang) OR (ky danh)) xay hoi. nhieu viec cam xuc va tinh he ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((ky dang) OR (ky danh)) xay hoi. nhieu viec cam xuc va tinh he ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ky dang) OR (ky danh)) xay hoi. nhieu viec cam xuc va tinh he ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: so sach ((ky dang) OR (ky danh)) xay hoi. nhieu viec cam xuc va tinh he ((cua te) or (cua tu))*.
