Thanks for the issue!

Looks like the relevant part is the JsonCodeBlock referenced in the doc viewer, the rendering logic is here.

return (
  <EuiCodeBlock aria-label={label} language="json" isCopyable paddingSize="s">
    {JSON.stringify(hit, null, 2)}
  </EuiCodeBlock>
);

We could probably find a way to hack this to render nested objects correctly, but I wonder why the underlying API is returning strings instead of objects? Is there some difference in how the documents are being processed under the hood here?

Marking as a good first issue and leaving open for now. In the spirit of making the issue approachable for newcomers, it would be nice to get some more detailed reproduction steps. I can work them out later if needed.
