Selecting From a Specific Predicate

So far, you've seen three different options for the "from" clause in a query:

  1. From a collection, "from": "actor"
  2. From a subject id, "from": 1893207
  3. From a unique two-tuple: "from": ["actor/name", "Angelina Jolie"]

You can also select every subject that has a specific predicate. For example, if you're interested in only movies that have the predicate movie/originalTitle, you can issue the query:

{
    "select": ["*"],
    "from": "movie/originalTitle"
}

The above query will return all the predicates from all subjects that have a movie/originalTitle.

Querying Only Predicates with _predicate/unique​

Can you select only the predicates that contain the _predicate/unique predicate?
