Working with 5.9?

Hi, Is anyone using this with 5.9? I see json with a few fields including url, title, but I was expecting to see page content, which I do not. Not sure if my expectations are inline. The concept is quite cool. I am hoping to use it to create client side site search with lunr.js

    "version": "https://jsonfeed.org/version/1.1",
    "user_comment": "This feed allows you to read the posts from this site in any feed reader that supports the JSON Feed format. To add this feed to your reader, copy the following URL -- https://10.0.0.73/json-2/feed/json/ -- and add it your reader.",
    "home_page_url": "https://10.0.0.73/json-2/",
    "feed_url": "https://10.0.0.73/json-2/feed/json/",
    "language": "en-US",
    "title": "Comments on: json"
}
