Hi,
I may have missed something, but in [this section of the Watcher documentation](https://www.elastic.co/guide/en/elastic-stack-overview/6.4/input-http.html#_using_templates_2), why `{{ctx.watch_id}}` refers to the index to query?
Thank you,
Chris

that is just an example to show, that you can use these context variables in the `search` input. Granted though, it does not make too much sense!
