+##########
+Search API
+##########
+
+You can search for resources at the top level, in a project or in a group.
+Searches are based on a scope (issues, merge requests, and so on) and a search
+string.
+
+Reference
+---------
+
+* v4 API:
+
+  + :attr:`gitlab.Gitlab.search`
+  + :attr:`gitlab.v4.objects.Group.search`
+  + :attr:`gitlab.v4.objects.Project.search`
+
+* GitLab API: https://docs.gitlab.com/ce/api/search.html
+
+Examples
+--------
+
+Search for issues matching a specific string::
+
+    # global search
+    gl.search('issues', 'regression')
+
+    # group search
+    group = gl.groups.get('mygroup')
+    group.search('issues', 'regression')
+
+    # project search
+    project = gl.projects.get('myproject')
+    project.search('issues', 'regression')
+
+The ``search()`` methods implement the pagination support::
+
+    # get lists of 10 items, and start at page 2
+    gl.search('issues', search_str, page=2, per_page=10)
+
+    # get a generator that will automatically make required API calls for
+    # pagination
+    for item in gl.search('issues', search_str, as_list=False):
+        do_something(item)
+
+The search API doesn't return objects, but dicts. If you need to act on
+objects, you need to create them explicitly::
+
+    for item in gl.search('issues', search_str, as_list=False):
+        issue_project = gl.projects.get(item['project_id'], lazy=True)
+        issue = issue_project.issues.get(item['iid'])
+        issue.state = 'closed'
+        issue.save()
