• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang ((x hoi) OR (x ho)). hieu va luat tuc ta thanh binh ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang ((x hoi) OR (x ho)). hieu va luat tuc ta thanh binh ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ((x hoi) OR (x ho)). hieu va luat tuc ta thanh binh ((cuu tre) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((x hoi) OR (x ho)). hieu va luat tuc ta thanh binh ((cuu tre) or (cua tre))*.
