• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang xa hoi. hieu va ((cao tuc) OR (cao suc)) va dinh vai ((cua triet) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. hieu va ((cao tuc) OR (cao suc)) va dinh vai ((cua triet) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. hieu va ((cao tuc) OR (cao suc)) va dinh vai ((cua triet) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. hieu va ((cao tuc) OR (cao suc)) va dinh vai ((cua triet) or (cua tu))*.
