Couchbase how to query an array

If I have Couchbase documents that look like this:

{
  "history": {
    "id": "123",
    "date": "today",
    "status_history": [
      {
        "code": "0",
        "message": "success",
        "status": "complete"
      }
    ],
    "other": "other"
  }
}

If I want to get all the documents from today I can do something like select * from 'my_bucket' where history.date = "today"

But how can I get something like status from status_history that is in an array structure?

select * from 'my_bucket' where history.status_history. status?? = "complete"

In addition to the [] syntax for specific array elements, you can also use ANY and ALL if you want to make sure that any element (or all of them) satisfies some condition. For example:

select * from my_bucket 
where any s in status_history satisfies s.status = 'complete' end;

You can address array elements using [] syntax.

For instance:

SELECT h.*
FROM my_bucket h
WHERE h.status_history[0].status = 'complete'
