• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach y)) nang co loi. hieu va cam xuc va thanh ((lai cua) or (hai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach y)) nang co loi. hieu va cam xuc va thanh ((lai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach y)) nang co loi. hieu va cam xuc va thanh ((lai cua) or (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) OR (sach y)) nang co loi. hieu va cam xuc va thanh ((lai cua) or (hai cua)) tre*.
