anchor.diff:  .The update API does not support versioning other than internal

  +External (version types `external` and `external_gte`) or forced (version type `force`)
   versioning is not supported by the update API as it would result in Elasticsearch 
   version numbers being out of sync with the external system.  Use the
   <<docs-index_,`index` API>> instead.

  // TEST[continued]
  
  We can add a tag to the list of tags (note, if the tag exists, it
  will still add it, since it's a list):

negative.code: The update API allows to update a document based on a script provided.
  The operation gets the document (collocated with the shard) from the
  index, runs the script (with optional script language and parameters),
  and indexes back the result (also allows to delete, or ignore the
  operation). It uses versioning to make sure no updates have happened
  during the "get" and "reindex".
