+Searching
+---------
+
+To search hosts, you can use a :http:get:`/api/v1/network/hosts/search` with your query
+passed using the ``q`` query parameter.
+
+- To search all hosts where the string "archiver" appears in any field, use ``q=archiver``::
+
+ curl -v -H "Authorization: Bearer $TOKEN" $URL/api/v1/network/hosts/search?q=archiver
+
+ Example response::

+The query string is passed directly to Elasticsearch. You can use exactly the same "mini-language" as when searching
+from the web user interface. Check the elasticsearch `query string syntax`_ for more details as well as the network
+:ref:`network-search` for the list of fields you can use.
+
+Note that if you pass ``q=name:arch``, this will not match *archiver* as elasticsearch uses keywords for string matching.
+In this case you'd need to use a wildcard: ``q=name:arch*``. Be aware that wildcard queries can use an enormous amount
+of memory and perform very badly.
