• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sac) OR (thu xac)) ky nang ma hoi. hieu ve cam duc van dinh ((cu va) or (su va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sac) OR (thu xac)) ky nang ma hoi. hieu ve cam duc van dinh ((cu va) OR (su va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) OR (thu xac)) ky nang ma hoi. hieu ve cam duc van dinh ((cu va) or (su va)) triet".
