Body properties #

documents: an array of object. Each object describes a document to update, by exposing the following properties:
- _id : ID of the document to replace
- body: partial changes to apply to the document

Response #

Returns an object containing 2 arrays: successes and errors

Each updated document is an object of the successes array with the following properties:

_id: document unique identifier
_source: document content
_version: updated document version
status: HTTP status code

Each errored document is an object of the errors array with the following properties:

document: original document that caused the error
status: HTTP error status code
reason: human readable reason

If strict mode is enabled, will rather return an error if at least one document has not been updated.
