Hi,

First of all, disclaimer: we had to move long before to `ES7.X` but we are doing right now, from `2.4`, shame on us.

Well, my case: I've found that `minimum_should_match` has a different behavior when the param given is bigger than optionals. Query:

ES 2.4:

> ```
> {
> "query": {
> "bool": {
> "should": [
> {
> "match": {
> "myfield": {
> "query": "my_search_value",
> "boost": 150
> }
> }
> }
> ],
> "minimum_should_match": 2
> }
> }
> }
> 
> ```

Here, in `ES2.4`, giving `"minimum_should_match": 2` and just 1 optional, it ignores the `"minimum_should_match": 2` and returns everything that matches.

BUT, now, the same in `ES7.1` gives no results, I have to put `"minimum_should_match": 1` if I want to get the results.

Looks like `ES2.4` was setting `minimum_should_match` at the maximum number of optionals and now it's not doing that anymore, is this possible?

I tried to find this in documentation and change logs but I couldn't find anything.

Any ideas?  
Thanks in advance
