• Performing a fuzzy search may retrieve terms with similar spellings: te sach y dang xay hoi. hieu ((va cam) or (ve cham)) tuc van hanh vi ((cua duc) OR (cua nuoc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang xay hoi. hieu ((va cam) OR (ve cham)) tuc van hanh vi ((cua duc) OR (cua nuoc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang xay hoi. hieu ((va cam) or (ve cham)) tuc van hanh vi ((cua duc) OR (cua nuoc))".
• Adding a wildcard symbol may retrieve word variants: te sach y dang xay hoi. hieu ((va cam) or (ve cham)) tuc van hanh vi ((cua duc) OR (cua nuoc))*.
