.. code-block:: yaml
use_default_settings: true
use_default_settings: True
server:
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
server:
bind_address: "0.0.0.0"
With ``use_default_settings: True``, each settings can be override in a similar way with one exception, the ``engines`` section:
With ``use_default_settings: True``, each settings can be override in a similar way, the ``engines`` section is merged according to the engine ``name``.
* If the ``engines`` section is not defined in the user settings, searx uses the engines from the default setttings (the above example).
* If the ``engines`` section is defined then:
* searx loads only the engines declare in the user setttings.
* searx merges the configuration according to the engine name.
In the following example, only three engines are available. Each engine configuration is merged with the default configuration.
In this example, searx will load all the engine and the arch linux wiki engine has a :ref:`token<private engines>`:
.. code-block:: yaml
use_default_settings: true
server:
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
engines:
- name: wikipedia
- name: wikidata
- name: ddg definitions
Another example where four engines are available. The arch linux wiki engine has a :ref:`token<private engines>`.
.. code-block:: yaml
use_default_settings: true
use_default_settings: True
server:
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
engines:
- name: arch linux wiki
tokens: ['$ecretValue']
- name: wikipedia
- name: wikidata
- name: ddg definitions
automatic update
----------------
It is possible to remove some engines from the default settings. The following example is similar to the above one, but searx doesn't load the the google engine:
The following comand creates or updates a minimal user settings (a secret key is defined if it is not already the case):
.. code-block:: yaml
.. code-block:: sh
use_default_settings:
engines:
remove:
- google
server:
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
engines:
- name: arch linux wiki
tokens: ['$ecretValue']
make SEARX_SETTINGS_PATH=/etc/searx/settings.yml user-settings.update
As an alternative, it is possible to specify the engines to keep. In the following example, searx has only two engines:
Set ``SEARX_SETTINGS_PATH`` to your user settings path.
.. code-block:: yaml
As soon the user settings contains an ``engines`` section, it becomes difficult to keep the engine list updated.
The following command creates or updates the user settings including the ``engines`` section:
.. code-block:: sh
make SEARX_SETTINGS_PATH=/etc/searx/settings.yml user-settings.update.engines
After that ``/etc/searx/settings.yml``
* has a ``secret key``
* has a ``engine`` section if it is not already the case, moreover the command:
* has deleted engines that do not exist in the default settings.
* has added engines that exist in the default settings but are not declare in the user settings.

keep_only:
- google
- duckduckgo
