• Performing a fuzzy search may retrieve terms with similar spellings: ((thu cac) OR (tu cac)) ky nang ma hoi. hieu van cam quoc ban anh va ((cua triet) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu cac) OR (tu cac)) ky nang ma hoi. hieu van cam quoc ban anh va ((cua triet) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu cac) OR (tu cac)) ky nang ma hoi. hieu van cam quoc ban anh va ((cua triet) or (cau tren))*".
