• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) ((nang xa) or (lang xa)) hoi. hieu va cam xuc va thanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) ((nang xa) OR (lang xa)) hoi. hieu va cam xuc va thanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) ((nang xa) or (lang xa)) hoi. hieu va cam xuc va thanh di cua tre".
