• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ve ((cam duc) OR (cao duc)) ((va thanh) OR (va tinh)) hoi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ve ((cam duc) OR (cao duc)) ((va thanh) or (va tinh)) hoi cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ve ((cam duc) OR (cao duc)) ((va thanh) or (va tinh)) hoi cua te*.
