Hello,

From the docs it's not clear if and how I can have multiple  
field\_value\_factors inside a function\_score. I would like to boost by  
ratingCount and by averageRating. I was expecting something like this:

```
"query": {
    "function_score": {
        "query" : {
            [..truncated...]
        },
        "field_value_factor": {
            "field": "ratingCount",
            "modifier": "log1p"
        },
        "field_value_factor": {
            "field": "avgRating",
            "modifier": "log1p"
        }
    }
}

```

What's the correct syntax for this, or what are (better) alternatives?
