- This is not to add any kind of sophisticated search feature but to
  have unions in a query result to see what comes out with example like:

    query {
      search(text: "spring", type: ARTIFACTREPOSITORY) {
        ... on ArtifactRepository {
          name
        }
        ... on Project {
          name
        }
      }
    }

  where you can use `text` as search field for names and optionally use `type`
  to limit results either to `ARTIFACTREPOSITORY` or `PROJECT`.
