• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu bich ha dung nguon co hoang minh ) OR ( thuat sach kha ke nguoi co trong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu bich ha dung nguon co hoang minh ) or ( thuat sach kha ke nguoi co trong minh ))*.
