Hi 

I just started playing around with elastic search and I am trying out the 
examples in the website with my data. I am trying to get custom scoring 
working. I am following the example from 
http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/query-dsl-function-score-query.html
 
But unable to get the example working

{
"query" : {
"function_score": {
    "boost_mode": "replace",
    "query": {"design.PRODUCT_DESC":"cool"},
    "script_score": {
        "params": {
            "param1": 2,
            "param2": 3.1
        },
        "script": "_score * doc['design.CLICKS'].value / pow(param1, 
param2)"
    }
}
}
}

I tried this query and i get the error 

Caused by: org.elasticsearch.index.query.QueryParsingException: [designs] 
[_na] query malformed, no field after start_object

Any help would be appreciated.
