Create Function Score Query from multiple queries

[trylika]

Currently we can only create FunctionScoreQuery() only from one query/filter, there is a need to pass multiple queries/filters

There is implemented objective functions addition in #247 . I will gonna change the query addition to similar way.

The plan is to behave like this:

$term = new TermQuery('price', 5);
$queryString = new QueryStringQuery('name', 'Bob');

$functionScore = new FunctionScoreQuery();
$functionScore->addQuery($term);
$functionScore->addQuery($queryString);
...

From the $search object there is a getter to get all queries.

ElasticsearchBundle/DSL/Query/QueryAwareTrait.php

Line 112 in 1390c9b

public function getQueries()

Is this will solve MatchMerge function score problem?
