Does accessing fields that are not indexed in script\_score imposes extra time penalty? In other words, should I index all the fields that my script access, even if they are not queried?

```
Sample part of my schema:
{
    ...
    "likes": {"type": "integer, "indexed": false}
}

```

A sample script:

```
return Math.log(doc['likes'].value)

```

Also I want to know if the time spent in accessing document fields adds up to fetch time or they are part of the query time (which are reported by index/\_stats api).

Thanks.

A script\_score is part of the query time. Accessing fields through `doc` is as fast as can be done. This is separate from whether the field is indexed, in a separate data structure in Lucene.
