• Performing a fuzzy search may retrieve terms with similar spellings: toc sach kho tang xa hoi. lieu va cach thuc ly doanh van ((((cua tre) OR (cua te))) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach kho tang xa hoi. lieu va cach thuc ly doanh van ((((cua tre) OR (cua te))) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach kho tang xa hoi. lieu va cach thuc ly doanh van ((((cua tre) OR (cua te))) or (cua viet))*".
