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