`create(parent, body=None, x__xgafv=None)`

    Creates a new document. This method is a [long-running operation](https://cloud.google.com/dialogflow/cx/docs/how/long-running-operation). The returned `Operation` type has the following method-specific fields: - `metadata`: KnowledgeOperationMetadata - `response`: Document

    Args:
      parent: string, Required. The knowledge base to create a document for. Format: `projects//locations//knowledgeBases/`. (required)
      body: object, The request body.
        The object takes the form of:

      "contentUri": "A String", # The URI where the file content is located. For documents stored in Google Cloud Storage, these URIs must have the form `gs:///`. NOTE: External URLs must correspond to public webpages, i.e., they must be indexed by Google Search. In particular, URLs for showing documents in Google Cloud Storage (i.e. the URL in your browser) are not supported. Instead use the `gs://` format URI described above.

`reload(name, body=None, x__xgafv=None)`

    Reloads the specified document from its specified source, content_uri or content. The previously loaded content of the document will be deleted.
