engine named "demo"::

    - name : demo
      engine : sqlite
      shortcut: demo
      categories: general
      result_template: default.html
      database : searx/data/filmliste-v2.db
      query_str :  >-
        SELECT title || ' (' || time(duration, 'unixepoch') || ')' AS title,
               COALESCE( NULLIF(url_video_hd,''), NULLIF(url_video_sd,''), url_video) AS url,
               description AS content
          FROM film
         WHERE title LIKE :wildcard OR description LIKE :wildcard
         ORDER BY duration DESC
      disabled : False
