That's my first experience in Go so it is probably not the best solution, but still it works :)

Finally I had some time to look into it.
What I have in mind is to use only one fields and depending on the type of the response of the HTTP call this is then either a simple string of a json structure.

If the HTTP response can be parsed as a json object then it will be returned as a json structure. Here I plan to use the mode parameter is in your PR. If the HTTP response cannot be parsed as a structure then the response as returned unchanged as a string.

What do you think?

[ddrozdov]

Thought about it, but this would make it impossible to use the same index name for both json and non-json responses because the body field type in Elasticsearch can't be a string and a group at the same time.

[christiangalsterer]

Valid point, will rethink it again.

Any news here?

[christiangalsterer]

I was busy with some activities in the last weeks. I will look into it the next days but most likely the PR will be merged unchanged or only smaller internal changes and keeping the approach using a dedicated field.

[christiangalsterer]

I merged your PR unchanged and a release 1.1.0 is available. Thanks very much for your contribution again.
