• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sach - sinh trong ((nghiep dung) or (nghiem song)) song van ((thanh ca) OR (thanh ha))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - sinh trong ((nghiep dung) OR (nghiem song)) song van ((thanh ca) OR (thanh ha))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - sinh trong ((nghiep dung) or (nghiem song)) song van ((thanh ca) OR (thanh ha))*".
