• Performing a fuzzy search may retrieve terms with similar spellings: so sach y sang xa hoi. lieu va ((tham soc) OR (cham soc)) ((va danh) or (va dinh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y sang xa hoi. lieu va ((tham soc) OR (cham soc)) ((va danh) OR (va dinh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y sang xa hoi. lieu va ((tham soc) OR (cham soc)) ((va danh) or (va dinh)) vi cua triet*".
