• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty tang ma hoi. hieu ve cham ((xuc va) or (thuc vat)) hanh lai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang ma hoi. hieu ve cham ((xuc va) OR (thuc vat)) hanh lai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang ma hoi. hieu ve cham ((xuc va) or (thuc vat)) hanh lai ((cua tre) OR (cua triet))*".
