 Search requests are processed in the ``search`` method. The ``$user`` object is the user who the result shall be generated for. ``$query`` gives context information like the **search term**, the **sort order**, the **route information**, the **size limit** of a request and the **cursor** for follow-up request of paginated results.
 
-The result is encapsulated in the ``SearchResult`` class that offers two static factory methods ``complete`` and ``paginated``. Both of these methods take an array of ``SearchResultEntry`` objects. ``SearchResultEntry`` is a static class that can be extended and used by the provider.
