Source Filtering Usage
editSource Filtering Usage
editAllows to control how the _source
field is returned with every hit.
By default operations return the contents of the _source
field unless
you have used the fields parameter or if the _source
field is disabled.
See the Elasticsearch documentation on Source Filtering for more detail.
