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