I'm trying to use a browser to make a query using the JSON format (Query DSL) on it.  
The goal is to test the performance between both type of query format.

My query DSL is the following:

> GET /\_search  
> {  
> "query":  
> { "match": "flood" }  
> }

It's working perfeclty. Now I'm trying to do the same query using the JSON query DSL format on URL (cause my futur query will be more complex).

> [http://localhost:9200/\_search?source={"query"%3A%20{"match"%3A%20{"text"%3A"flood"}}}&source\_content\_type="application%2Fjson"](http://localhost:9200/_search?source=%7B%22query%22%3A%20%7B%22match%22%3A%20%7B%22text%22%3A%22flood%22%7D%7D%7D&source_content_type=%22application%2Fjson%22)

But when I do that, I encounter some problems and I cannot access to my results.

```
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"invalid Content-Type header [\"application/json\"]"}],"type":"illegal_argument_exception","reason":"invalid Content-Type header [\"application/json\"]"},"status":400}

```

Any idea ? my source body is a json format, I don't understand why I have this illegal\_argument\_exception.
