• answer: chunks of answer, may be Markdown format to support rich text, for example: Tables. For detailed_citation answer, the span tag chunk may be as follows:

  autobiography captured the pre-Nazi Europe[<span data-index="0">1</span>]
  

  The tag attr data-index is the index of the source in source_info array, which is used to highlight the source of the previous answer sentences in your PDF viewer. The highlighting method is same as source_info, and just use slice of source_info array as parameter.

• id: id of the question, you can use it to GET /questions/{question_id} later.

Please note: you should store id in your database, because we don't have a GET /questions/list API to list all questions for now.

• source_info: only responses in the last chunk of server-sent events mode, may be an empty list. So if the last chunk doesn't contain source_info attr, it means error occurred. Page number may not be ordered, you can use this information to highlight the source of specific upload_id document of the answer in your PDF viewer, by
  calling drawSources method of our DOCViewerSDK, and converting source_info to Source parameter.
