Hi guys, I've a problem and I'm stuck:

We have a page called 'Jobs und Karriere' (german) and when I search for 'Jobs' I get the expected result, but searching for 'Karriere' doesn't find anything.  
Here's my query:

```auto
# Query
{
    "query": {
        "bool": {
            "must": [{
                "match": {
                    "_all": {
                        "query": "karriere",
                        "operator": "and",
                        "boost": 2,
                        "fuzziness": 1
                    }
                }
            }, {
                "match": {
                    "type": {
                        "query": "pages"
                    }
                }
            }],
            "should": [{
                "match": {
                    "title": {
                        "query": "karriere",
                        "boost": 20,
                        "fuzziness": 1
                    }
                }
            }, {
                "match": {
                    "content": {
                        "query": "karriere",
                        "fuzziness": 1
                    }
                }
            }],
            "minimum_should_match": 1
        }
    },
    "from": 0,
    "size": 4,
    "_source": ["title", "url", "content", "created", "category"]
}

```

I tried to debug the query against the matching document-id (with the explain-API) with no luck. Then I tried to debug the problem locally (I was working on staging before) and I got the expected result for both queries, so there must be some difference, maybe someone can help me or point me in the right direction.

I get results (even for staging) when I set the analyzer directly in my query like so:

```auto
query -> bool -> must -> match -> _all -> "analyzer": "EdgenGram_analyzer"
query -> bool -> should -> match -> title -> "analyzer: "nGram_analyzer"

```

What I don't understand: `nGram_analyzer` is already set for the `title` field and `EdgenGram_analyzer` for `_all` (see mappings below), is it possible that they are overwritten at some point?
