I am trying to bind Grafana 5.2.1 with ES 5.5.  
I success to make an ES Data Source and it works perfectly ; index and time field are read correctly without error).  
Then, I am facing a weird issue ; when I create a dashboard then a graph (simple histogram), I get an HTTP 400 "bad request", with the reason "Validation Failed: 1: no requests added;".

I can reproduce this exception throught a curl like this, where all stand in one line :

```
curl -XPOST 'http://#####:9200/_msearch' -u 'user:password' -d '{"index" : "my_index"} {"query" : {"match_all" : {}}, "from" : 0, "size" : 10}'

```

And if I do the curl like this (with breaking lines), it works perfectly :

```
curl -XPOST 'http://#####:9200/_msearch' -u 'user:password' -d '
{"index" : "my_index"}
{"query" : {"match_all" : {}}, "from" : 0, "size" : 10}

'

```

So, I presume that Grafana tranforms the query and makes something wrong.  
I did not see anything about my trouble, so I'll be pleased if anyone can help me. Thanks.
