• Performing a fuzzy search may retrieve terms with similar spellings: su sach thi hang xa hoi. hieu ve ((cham tuc) OR (nham thuc)) va dan loai ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thi hang xa hoi. hieu ve ((cham tuc) OR (nham thuc)) va dan loai ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thi hang xa hoi. hieu ve ((cham tuc) OR (nham thuc)) va dan loai ((dua tren) or (cuu tre))*".
