field_value_factor

Summary of problem or feature request

I am new to Elasticsearch. Ive been stuck for hours trying to figure out how to rank search results based on another search field.

In the example below, I am trying to search for product, but want the field "score" to affect the results. It is failing with "failed to create query".

I have tried using "random_score" (commented lines), and this works perfectly.

Code snippet of problem

#$randomScore = new \stdClass();
$params['body'] = array(
    'query' => array(
        'function_score' => array(
            'functions' => array(
                array("field_value_factor" => array('field' => 'score'))
                #array("random_score" => $randomScore)

            ),
            'query' => [
                'match' => [
                    'product' => 'shoe'
                ]
            ]
        )
    )
);

Fixed.The syntax above is correct. Turned out the product-field was set to string.
