Elasticsearch query not returning anything

I have the following document indexed but when I run the search it's not returning anything, I was wondering if its an issue with the query. I am trying to search for any of the nested messages that have the word dogs in it. Here is the document:

{
"_index": "thread_and_messages",
"_type": "thread",
"_id": "3",
"_score": 1.0,
"_source": {
    "thread_id": 3,
    "thread_name": "I play the guitar",
    "created": "Wed Apr 13 2016",
    "thread_view": 2,
    "first_nick": "Test User",
    "messages": [{
        "message_text": " I like dogs",
        "message_id": 13,
        "message_nick": "Test"
    }],
    "site_name": "Test Site"
}
}

Here is the query I am running when I run the curl command:

{
"function_score": {
    "functions": [{
        "field_value_factor": {
            "field": "thread_view",
            "modifier": "log1p",
            "factor": 2
        }
    }],
    {"query": {
        "bool": {
            "should": [{
                "match": {
                    "thread_name": "dogs"
                }
            }, {
                "nested": {
                    "path": "messages",
                    "query": {
                        "bool": {
                            "should": [{
                                "match": {
                                    "messages.message_text": "dogs"
                                }
                            }]
                        }
                    },
                    "inner_hits": {}
                }
            }]
        }
    }
}
}
