Quick note about "ctx.\_now" w.r.t "\_update\_by\_query". Follow-up to [Elasticsearch Update by Query using CTX](https://discuss.elastic.co/t/elasticsearch-update-by-query-using-ctx/112176)

I saw this too, today, and was surprised since "\_update" does support "ctx.\_now", but "\_update\_by\_query" apparently does not. Solution may be to just use "currentTimeMillis()".

At first I thught that's a bug, but the "\_update\_by\_query" documentation does not really mention it, unlike "\_update".
