+    DocumentCloud paginates search results. By default the search methods returns
+    from all pages. If you want to restrict the number of pages that are searched
+    or retrieve a specific page you should provide some combination of the following
+    keyword arguments.
+
+        >>> obj_list = client.documents.search('Ruben Salazar', page=1, per_page=10)
+        # You can guess that will do.
+        >>> len(obj_list) == 10
+        >>> True
+
+    By default, the search returns three mentions of the result in each document.
+    You can increase that number up to 10 by modifying the keyword argument.
+
+        >>> client.documents.search('Ruben Salazar', mentions=10)
+
+    Unlike when you get a document directly via id, the key/value dictionaries
+    they can be assigned are not provided by default in search results.
+
+    To have them included, switch the following keyword argument.
+
+        >> client.documents.search('Ruben Salazar', data=True)
