ElasticSearch: how to define custom analyzers with REST API?

Question

I want to define custom analyzers through the REST API (I'm using a hosted service - http://searchbox.io ), but I can't understand how to do it.

I'm trying to create a PUT request to /myindex/_settings with the following:

   index: {
            analysis: {
                    analyzer: {
                            "my_analyzer": {
                                    type: "snowball",
                                    language: "English"
                            }
                    }
            }
    }

but it doesn't work, if I index a field with "my_analyzer" set as the analyzer I'm getting an error that it doesn't exist..

after you've put the settings, what happens when you try to get them back using get settings api? /myindex/_settings ? — javanna

I see general index settings, nothing related to analysis and analyzers. — Gal Ben-Haim

I found the answer - those settings must be set when creating the index.

so a POST request to /myindex did it.

Correct, otherwise you need to close the index before adding the analyzer and then reopen the index. Have a look here.

Could you elaborate on this? Maybe post a small complete dictionary you were using to specify this? I'm stuck at this point :-/
