I am using the river plugin for CouchDB and when I execute the following curl command:

    curl -XPUT 'localhost:9200/_river/blog/_meta' -d '{
    "type" : "couchdb",
    "couchdb" : {
    "host" : "localhost",
    "port" : 5984,
    "db" : "blog",
    "filter" : null
    },
    "index" :{
    "analysis" :{

        "analyzer" :{ 
            "whitespace" :{ 
                "type" : "whitespace",
                "filter":"lowercase"
            },
            "ox_edgeNGram" :{
                    "type" : "custom",
                    "tokenizer" : "ox_t_edgeNGram",
                    "filter" : ["lowercase"]
            },
            "ox_NGram" :{
                    "type" : "custom",
                    "tokenizer" : "ox_t_NGram",
                    "filter" : ["lowercase"]
            }

        },

        "tokenizer" :{
                "ox_t_edgeNGram":{
                        "type":"edgeNGram",
                        "min_gram":2,
                        "max_gram":25,
                        "side":"front"
                },
                "ox_t_NGram":{
                        "type":"NGram",
                        "min_gram":2,
                        "max_gram":25
                }
        }
    }
}
}'

receive the response:

    {"ok":true,"_index":"_river","_type":"blog","_id":"_meta","_version":1}

The problem I have, is when I want to view the settings in the browser and go to: http://localhost:9200/blog/_settings?pretty=true

The json that is returned is as follows, but I'm expecting information regarding the analyzer etc. that I thought I created.

Returned JSON:

    {
    blog: -{
    settings: -{
    index.number_of_shards: "5"
    index.number_of_replicas: "1"
        }
      }
    }

It should also be noted that when I create a blog index without using the river and run a curl command to input the analysis information, I do receive a response from the browser indicating the settings that I input.

How can I set the default settings of a an index when using the River plugin?
