• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky tang ma hoi. hieu he nam thu xac ((danh sai) OR (danh bat)) ((cua viet) or (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang ma hoi. hieu he nam thu xac ((danh sai) OR (danh bat)) ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang ma hoi. hieu he nam thu xac ((danh sai) OR (danh bat)) ((cua viet) or (ca viet))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky tang ma hoi. hieu he nam thu xac ((danh sai) OR (danh bat)) ((cua viet) or (ca viet))*.
