    """Load from `EverNote`.
    Loads an EverNote notebook export file e.g. my_notebook.enex into Documents.
    Instructions on producing this file can be found at
    https://help.evernote.com/hc/en-us/articles/209005557-Export-notes-and-notebooks-as-ENEX-or-HTML
    Currently only the plain text in the note is extracted and stored as the contents
    of the Document, any non content metadata (e.g. 'author', 'created', 'updated' etc.
    but not 'content-raw' or 'resource') tags on the note will be extracted and stored
    as metadata on the Document.
    Args:
        file_path (str): The path to the notebook export with a .enex extension
        load_single_document (bool): Whether or not to concatenate the content of all
            notes into a single long Document.
        If this is set to True (default) then the only metadata on the document will be
            the 'source' which contains the file name of the export.
