• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach y)) dang xay hoi. hieu va cam xuc va thanh hoa ((cua tre) or (cau trieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach y)) dang xay hoi. hieu va cam xuc va thanh hoa ((cua tre) OR (cau trieu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach y)) dang xay hoi. hieu va cam xuc va thanh hoa ((cua tre) or (cau trieu))*".
