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