I'm not sure what the first `match` clause is supposed to do. Why search for an empty string with `fuzziness` set to `0` and the `operator` set to `and`? If I execute that query agains the document that you posted it does not match the document. This clause is the cause of the entire query not matching your document.

```auto
GET bupstest9/_search
{
  "query": {
    "match": {
      "source": {
        "query": "",
        "fuzziness": "0",
        "operator": "and"
      }
    }
  }
}

```

PS Please format the code that you post here, as described [here](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It makes it much easier to read. 🙂
