regex in body of api test : Im testing api with https://cloud.google.com/datastore/docs/reference/data/rest/v1/projects/lookup

The following brings a found result with data. I would like to use a regex expression with bring back all records with name having the number 100867. All my attempts result wit a missing result set.
i.e. change to  "name": "/1000867.*/"
            `            {
            "keys": [
                {
                "path": [
                    {
                    "kind": "Job",
                    "name": "1000867:100071805:1"
                    }
                ]
                }
            ]
            }`
