• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang xa hoi. ((thi van) OR (thi hanh)) ((lam xuc) or (lam duoc)) va danh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. ((thi van) OR (thi hanh)) ((lam xuc) OR (lam duoc)) va danh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. ((thi van) OR (thi hanh)) ((lam xuc) or (lam duoc)) va danh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. ((thi van) OR (thi hanh)) ((lam xuc) or (lam duoc)) va danh vai cua triet*.
