Let's say I have a parent/child relationship, Blog posts (parent) and comments (child), posts contain the post text and comments contain comment text.

I want to offer search functionality that will return comments, but will consider and score based on the content of **both** the comment text and the parent post text eg with these documents (shown as nested to save space)

```
post:
  text: foo
  comments: [
    { date: today, text: "Great post" }
  ]

post:
  text: bar
  comments: [
    { date: today, text: "Great post, as was the earlier one about foo" }
  ]

```

If the term we're looking for is 'foo' both comments will be in the results.

I've seen has\_child/has\_parent queries and filters but they appear only to consider the fields of **either** the parent or the child, I want to consider both.

What kind of query can I use to achieve this without resorting to a nested relationship?
