It looks like it highlights numbers from your range query. Try replacing the boolean query in the first “must” clause with this:

"filtered": {
    "query": {
        "query_string": {
            "query": "official",
            "default_field": "Content"
        }
    }, 
    "filter": {
        "range": {
            "actualTimeStamp": {
                "from": "08-04-2011 23:37:06",
                "to": "16-11-2012 00:00:00"
            }
        }
    }
}
