• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach thu) OR (sach thue)) lang xa hoi. hieu van cam tuc va danh ((sai cua) or (lai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach thu) OR (sach thue)) lang xa hoi. hieu van cam tuc va danh ((sai cua) OR (lai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach thu) OR (sach thue)) lang xa hoi. hieu van cam tuc va danh ((sai cua) or (lai cua)) te*".
