Elastic response filtering

[mhernik]

Please add response filtering as described here
https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html
I think it's only additional option in Serach class.

It should be possible to add filter_path to the valid options here: https://github.com/ruflin/Elastica/blob/master/lib/Elastica/Search.php#L280 This would allow to pass the filter_path through the options param in search(..., ...). Interested to open a PR for it?

@mhernik Awesome: #1292 Read the issue first before I saw the PR :-)

Response filtering is supported, and as you guessed it is an option on Search:

$search = new \Elastica\Search($client);
$search->setOption(\Elastica\Search::OPTION_FILTER_PATH, 'hits.hits._source');

Search::OPTION_FILTER_PATH is accepted by Search::validateOption() and forwarded to Elasticsearch as the filter_path query parameter.

Closing as implemented.
