How to use deleteByQuery function

[nignatov]

Hello,

I'm trying to delete some documents using the deleteByQuery function but I'm receiving ActionRequestValidationException[Validation Failed: 1: source is missing;].
From the function description I cannot understand what is wrong with the parameters I'm sending. I've tried to pass 'source' parameter also but the same exception occur.
What is the correct syntax here? I'm using 1.0 version of the library.

$params['index'] = 'yyyy';
$params['type'] = 'xxxx';
$params['body']['query'] = array(
'term' => array(
'entity.entity_id' => $id
)
);

try {
$response = $client->deleteByQuery($params);
}
catch (Exception $e) {
....
}

Ahhh, stupid me.
The problem comes from my proxy, no issue with deleteByQuery().
Sorry for disturbing.
