• Performing a fuzzy search may retrieve terms with similar spellings: tu sach truc nao va hoa. thi van ((cam cuu) OR (cham cuu)) ban hanh vi ((cua triet) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach truc nao va hoa. thi van ((cam cuu) OR (cham cuu)) ban hanh vi ((cua triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach truc nao va hoa. thi van ((cam cuu) OR (cham cuu)) ban hanh vi ((cua triet) or (cua te))".
