• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang mam) OR (dang mau)) hoa. hieu van cam ((xuc va) or (duc va)) thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang mam) OR (dang mau)) hoa. hieu van cam ((xuc va) OR (duc va)) thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang mam) OR (dang mau)) hoa. hieu van cam ((xuc va) or (duc va)) thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((dang mam) OR (dang mau)) hoa. hieu van cam ((xuc va) or (duc va)) thanh vai cua tre*.
