Hello,

I'm using Elasticsearch and Kibana 5.3.1

When I try to create an index pattern inside the Management tab, Kibana do not find any of my patterns while the indices exist, and all of them contain data. The error I get is:

```
{
    error: {
        root_cause: [
            {
                type: "illegal_argument_exception",
                reason: "request [/touristic*/_mapping/field/*] contains unrecognized parameter: [_]"
            }
        ],
        type: "illegal_argument_exception",
        reason: "request [/touristic*/_mapping/field/*] contains unrecognized parameter: [_]"
    },
    status: 400
}

```

And the query Kibana is sending to Elasticsearch is:

```
http://host:port/touristic*/_mapping/field/*?_=1495645374162&ignore_unavailable=false&allow_no_indices=false&include_defaults=true

```

Indeed, if I remove the underscore parameter, the query works well. What is this underscore parameter? How to get rid of this parasite parameter?

Thanks in advance for any help!
