Source filtering

edit

Allows 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.

You can turn off _source retrieval by using the _source parameter:

To disable _source retrieval set to false:

{
    "_source": false,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

The _source also accepts one or more wildcard patterns to control what parts of the _source should be returned:

For example:

{
    "_source": "obj.*",
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

Or

{
    "_source": [ "obj1.*", "obj2.*" ],
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

Finally, for complete control, you can specify both include and exclude patterns:

{
    "_source": {
        "include": [ "obj1.*", "obj2.*" ],
        "exclude": [ "*.description" ]
    },
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
