• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((2 dang) OR (b dang)) ma hoa. hieu van ((nam duoc) or (cam xuc)) va thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((2 dang) OR (b dang)) ma hoa. hieu van ((nam duoc) OR (cam xuc)) va thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((2 dang) OR (b dang)) ma hoa. hieu van ((nam duoc) or (cam xuc)) va thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((2 dang) OR (b dang)) ma hoa. hieu van ((nam duoc) or (cam xuc)) va thanh vai cua tre*.
