Hello,

I am writing a `dis_max` query for stacking up the results from different queries. The first query usually returns only one result and I'd like to have that document on top on my results. So I put the query inside a `constant_score` with a bigger score.

```
{
  "query": {
    "constant_score": {
      "query": {
        "bool": {
          "must": [
            {
              "match_phrase": {
                "article_title": {
                  "query": "elasticsearch server",
                  "slop": 60
                }
              }
            }
          ],
          "should": [
            {
              "match": {
                "article_title.raw": "elasticsearch server"
              }
            }
          ],
          "filter": [
            {
              "term": {
                "article_status": "publish"
              }
            },
            {
              "term": {
                "article_type": "document"
              }
            }
          ]
        }
      },
      "boost": 3
    }
  }
}

```

This query doesn’t return any results, but if I remove `constant_score` and execute the query again I get my expected results. So I think the proble is not the query but how I use `constant_score`.

As fas I know `constant_score` should return the document from the inner query, does the query looks ok?

Anyway here my complete query, maybe my approach is not great, right?

```
{
  "query": {
    "dis_max": {
      "tie_breaker": 0.7,
      "queries": [
        {
          "query": {
            "constant_score": {
              "query": {
                "bool": {
                  "must": [
                    {
                      "match_phrase": {
                        "article_title": {
                          "query": "elasticsearch server",
                          "slop": 60,
                          "operator": "and",
                          "minimum_should_match": "80%"
                        }
                      }
                    }

```
           {
              "match": {
                "article_title.raw": "elasticsearch server"
              }
            }

```

found the problem, was on my data, not the query.
