**Additional Notes**

* All documents you list will be used for question answering.
* Question answering can work with any number of documents.&#x20;
* All documents need to be processed before question answering can be performed. This occurs automatically the first time you use the feature in experience mode.
  * When the document is processing, the system will notify you it is unable to answer your question.
  * This only occurs once per document.  Using the document in another or subsequent experiences will not require re-processing.
