      The Lens API exposes the full corpus of Lens scholarly works and patents
      via a REST interface. Search endpoints accept Elasticsearch-style query
      DSL via POST or simple Lucene query strings via GET, with cursor-based
      pagination, field projection, sorting, stemming controls, and patent
      family grouping. Authentication is via a bearer token issued from the
      Lens user profile.
