You can configure each text analyzer to serve a different purpose to help the email bot respond correctly. For example, you can configure the first text analyzer to detect only entities or topics in the email body, another one to detect only entities or topics in the email attachments, and a third one to detect entities or topics in both the email body and attachments.
