• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty hang x hoi. hieu ((van cac) or (van cau)) luc gia thanh ((de cua) OR (le cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang x hoi. hieu ((van cac) OR (van cau)) luc gia thanh ((de cua) OR (le cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang x hoi. hieu ((van cac) or (van cau)) luc gia thanh ((de cua) OR (le cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hang x hoi. hieu ((van cac) or (van cau)) luc gia thanh ((de cua) OR (le cua)) triet*.
