[[search-request-source-filtering]]
=== Source filtering
added[1.0.0.Beta1]
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,js]
--------------------------------------------------
{
"_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,js]
--------------------------------------------------
{
"_source": "obj.*",
"query" : {
"term" : { "user" : "kimchy" }
}
}
--------------------------------------------------
Or
[source,js]
--------------------------------------------------
{
"_source": [ "obj1.*", "obj2.*" ],
"query" : {
"term" : { "user" : "kimchy" }
}
}
--------------------------------------------------
Finally, for complete control, you can specify both include and exclude patterns:
[source,js]
--------------------------------------------------
{
"_source": {
"include": [ "obj1.*", "obj2.*" ],
"exclude": [ "*.description" ],
}
"query" : {
"term" : { "user" : "kimchy" }
}
}
--------------------------------------------------
