• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach tu)) ((nang ma) or (tang ma)) hoi. hieu ve cac loc va danh di cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) ((nang ma) OR (tang ma)) hoi. hieu ve cac loc va danh di cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) ((nang ma) or (tang ma)) hoi. hieu ve cac loc va danh di cua tu*".
