I have a shingle filter:

```auto
"custom_shingle_filter": {
    "type": "shingle",
    "max_shingle_size": 2,
    "min_shingle_size": 2,
    "token_separator": "",
    "output_unigrams": true
}   

```

Then I use this shingle filter in my search analyzer:

```auto
"custom_search_analyzer": {
    "type": "custom",
    "tokenizer": "whitespace",
    "filter": [
        "custom_shingle_filter"
    ]
}

```

When I run `validate` API to my query:

```auto
GET /test_index/test_type/_validate/query?explain=true
{
  "query" : {
    "match" : {
      "test_field" : {
        "query" : "macbook pro",
        "operator" : "and",
        "analyzer" : "custom_shingle_filter"
      }
    }
  }
}

```

In 5.2.2, I got:  
`+Graph(+test_field:macbook +test_field:pro, test_field:macbookpro, hasBoolean=true, hasPhrase=false)`  
It means it will query (`macbook` and `pro`) or `macbookpro`  
But in 5.1.2:  
`+Synonym(test_field:macbook test_field:macbookpro) +test_field:pro`  
It means it will query (`macbook` or `macbookpro`) and `pro` ?????

The result in 5.2.2 makes sense to me, but I got different behaviour on 5.1.2 and (unfortunately) it's what we have on production.  
Any idea?  
Thanks.

This is very likely due to [https://github.com/elastic/elasticsearch/pull/21517](https://github.com/elastic/elasticsearch/pull/21517)
