• Performing a fuzzy search may retrieve terms with similar spellings: te sac ((ky lang) or (ky tang)) xa hoi. lieu va nam ((thuoc va) OR (thuc va)) thanh doi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ((ky lang) OR (ky tang)) xa hoi. lieu va nam ((thuoc va) OR (thuc va)) thanh doi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ((ky lang) or (ky tang)) xa hoi. lieu va nam ((thuoc va) OR (thuc va)) thanh doi cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ((ky lang) or (ky tang)) xa hoi. lieu va nam ((thuoc va) OR (thuc va)) thanh doi cua triet*.
