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