Answer 1

Got it working by adding limit filter

"filtered": {
    "filter": {
        "limit": {
           "value": 200
        }
    }
}

A limit filter limits the number of documents (per shard) to execute on. More info: https://www.elastic.co/guide/en/elasticsearch/reference/1.3/query-dsl-limit-filter.html
