• Performing a fuzzy search may retrieve terms with similar spellings: su sai ky nang ma hoi. hieu ve chat ((xuc va) OR (luc va)) hanh ((di va) or (doi va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang ma hoi. hieu ve chat ((xuc va) OR (luc va)) hanh ((di va) OR (doi va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang ma hoi. hieu ve chat ((xuc va) OR (luc va)) hanh ((di va) or (doi va)) triet".
