{
    "revisions": [
        {
            "is_rfc": false,
            "revision": "2019-09-11"
        },
        {
            "is_rfc": true,
            "revision": "2019-09-11"
        },
        {
            "is_rfc": false,
            "revision": "2019-04-10"
        },
        {
            "is_rfc": false,
            "revision": "2019-03-21"
        },
        {
            "is_rfc": false,
            "revision": "2018-11-22"
        },
        {
            "is_rfc": false,
            "revision": "2018-11-06"
        }
    ]
}

I've also seen it for other modules which I don't remember right now.

It seems that this script from https://github.com/YangCatalog/backend/pull/705 somehow didn't work as intended and left some documents without the "rfc" field.

[richardzilincikPantheon]

Searching ES only returns 10 results by default, this means that the 'rfc' property was only set on the first 10 results. Needs to be done through an update by query instead.

Fixed the script https://gist.github.com/richardzilincikPantheon/e7fa472f1ef9f54988465be93f883238, the issue should be resolved after it's run in production.
