• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty mang may hoi. hieu ((tu cham) or (toc cham)) ((loc van) OR (lo van)) hanh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty mang may hoi. hieu ((tu cham) OR (toc cham)) ((loc van) OR (lo van)) hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty mang may hoi. hieu ((tu cham) or (toc cham)) ((loc van) OR (lo van)) hanh va cua tre*".
