Hi,

I attempt save a search template with a term query.

```
POST _scripts/test-json
{
  "script": {
    "lang": "mustache",
    "source": {"query": {"filter": {"bool": {"must": [{"terms": {"beat.hostname": {{#tojson}}hostname{{/tojson}} } }] } } } }
  }
}

```

But I got a syntax error without the double quote.

I saw the issue in github.  
[https://github.com/elastic/elasticsearch/issues/21648](https://github.com/elastic/elasticsearch/issues/21648)

I changed the template like the sample in the issue, it's no syntax error. But I can not get the result.

```
POST _scripts/test-json
{
  "script": {
    "lang": "mustache",
    "source": {"query": {"filter": {"bool": {"must": [{"terms": {"beat.hostname": ["{{hostname}}"] } }] } } } }
  }
}

```

And then I changed the template:

```
POST _scripts/test-json
{
  "script": {
    "lang": "mustache",
    "source": {"query": {"filter": {"bool": {"must": [{"terms": {"beat.hostname": ["{{#tojson}}hostname{{/tojson}}}}"] } }] } } } }
  }
}

```

After call is, I got a runtime error.

```
  {
    "type": "json_parse_exception",
    "reason": "Unexpected character ('h' (code 104)): was expecting comma to separate Array entries\n at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@396f6738; line: 1, column: 190]"
  }

```

How could I use the terms in a pre-registered template?

Thank you.
