• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu hang xa hoi. lieu va ((cam tuc) OR (nam thuc)) va hoang ((di su) or (da su)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu hang xa hoi. lieu va ((cam tuc) OR (nam thuc)) va hoang ((di su) OR (da su)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu hang xa hoi. lieu va ((cam tuc) OR (nam thuc)) va hoang ((di su) or (da su)) triet*".
