How to update
=============

How to update depends on the :ref:`installation` method.  If you have used the
:ref:`installation scripts`, use the ``update`` command from the :ref:`searxng.sh`
script.

.. code:: sh

    sudo -H ./utils/searxng.sh instance update

SearXNG is a *rolling release*; each commit to the master branch is a release.
SearXNG is growing rapidly, the services and opportunities are change every now
and then, to name just a few:

- Bot protection has been switched from filtron to SearXNG's :ref:`limiter
  <limiter>`, this requires a :ref:`Redis <settings redis>` database.

- To save bandwidth :ref:`cache busting <static_use_hash>` has been implemented.
  To get in use, the ``static-expires`` needs to be set in the :ref:`uwsgi
  setup`.

To stay tuned and get in use of the new features, instance maintainers have to
update the SearXNG code regularly (see :ref:`update searxng`).  As the above
examples show, this is not always enough, sometimes services have to be set up
or reconfigured and sometimes services that are no longer needed should be
uninstalled.

Here you will find a list of changes that affect the infrastructure.  Please
check to what extent it is necessary to update your installations:

:pull:`1595`: ``[fix] uWSGI: increase buffer-size``
  Re-install uWSGI (:ref:`searxng.sh`) or fix your uWSGI ``searxng.ini``
  file manually.


Check after Installation
------------------------

Once you have done your installation, you can run a SearXNG *check* procedure,
to see if there are some left overs.  In this example there exists a *old*
``/etc/searx/settings.yml``::

   $ sudo -H ./utils/searxng.sh instance check

   SearXNG checks
