Elasticsearch 2.3. I am firing this query to update every doc in an index based on a condition.

```
{
"query": {
  "bool": {
     "must": [
        {
          "match_all": {}
        }]}},
  "script" : 
  { 
     "inline" : "if (ctx._source.url.endsWith('a=6')) ctx.op = 'none' else ctx._source.url = ctx._source.url + '&b=3'"
  }
}

```

As stated [here](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/docs-update.html), I am using `ctx.op = 'none'` to avoid updating the docs that do not match the condition.

I am getting

> Invalid op [none]

Full error:

```
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "Invalid op [none]"
}
],
"type": "illegal_argument_exception",
"reason": "Invalid op [none]"
},
"status": 400

```

Seems to be so simple that I am pretty lost. Thanks for your help.

The correct operation is `noop`, not `none`. The docs seems to be outdated.
