Using ES 5.1.1 (Edit: Just upgraded to 5.5.0, same behaviour)

I'm getting some odd behaviour when mixing minimum\_should\_match with differing analyzers, and was wondering if anyone had any insights.

Simplified down, my issue is this:

I have two analysers. One has stopwords (A), and one doesn't(B).

There are two fields.  
" **title**", which uses analyser A (the one with stopwords)

" **keywords**", which uses analyser B.

The stopwords list includes the word "_cat_".

There is one record:  
`{"title": "Hello world", "keywords": "dog"}`

I'm doing the following query:

```
"query" : {
	"multi_match": {
		"query" : "hello cat",
		"type" : "cross_fields",
		"fields": ["title", "keywords"],
		"minimum_should_match" : 2
	}
}

```

Now, in theory there should be no results. The word "cat" doesn't appear anywhere in the data, and minimum\_should\_match is set to 2. Yet this result is returned.

If I change the query term to:  
"_hello cheese_", I rightly get 0 results.

Does anyone know why is this? Any suggestions on how can I work around it to get the desired result would be appreciated?  
Thanks
