|

|
||||
A few more options are possible, but they are pretty specific to some
|
||||
engines, and so won't be described here.
|
||||
|
||||
|
||||
.. _settings location:
|
||||
|
||||
settings.yml location
|
||||
=====================
|
||||
|
||||
First, searx will try to load settings.yml from these locations:
|
||||
|
||||
1. the full path specified in the ``SEARX_SETTINGS_PATH`` environment variable.
|
||||
2. ``/etc/searx/settings.yml``
|
||||
|
||||
If these files don't exist (or are empty or can't be read), searx uses the :origin:`searx/settings.yml` file.
|
||||
|
||||
.. _ settings use_default_settings:
|
||||
|
||||
use_default_settings
|
||||
====================
|
||||
|
||||
.. note::
|
||||
|
||||
If searx is cloned from a git repository, most probably there is no need to have an user settings.
|
||||
|
||||
The user defined settings.yml can relied on the default configuration :origin:`searx/settings.yml` using ``use_default_settings: True``.
|
||||
|
||||
In the following example, the actual settings are the default settings defined in :origin:`searx/settings.yml` with the exception of the ``secret_key`` and the ``bind_address``:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
use_default_settings: True
|
||||
server:
|
||||
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
|
||||
bind_address: "0.0.0.0"
|
||||
|
||||
With ``use_default_settings: True``, each settings can be override in a similar way, the ``engines`` section is merged according to the engine ``name``.
|
||||
|
||||
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: arch linux wiki
|
||||
tokens: ['$ecretValue']
|
||||
|
||||
It is possible to remove some engines from the default settings. The following example is similar to the above one, but searx doesn't load the the google engine:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
use_default_settings:
|
||||
engines:
|
||||
remove:
|
||||
- google
|
||||
server:
|
||||
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
|
||||
engines:
|
||||
- name: arch linux wiki
|
||||
tokens: ['$ecretValue']
|
||||
|
||||
As an alternative, it is possible to specify the engines to keep. In the following example, searx has only two engines:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
use_default_settings:
|
||||
engines:
|
||||
keep_only:
|
||||
- google
|
||||
- duckduckgo
|
||||
server:
|
||||
secret_key: "uvys6bRhKHUdFF5CqbJonSDSRN8H0sCBziNSrDGNVdpz7IeZhveVart3yvghoKHA"
|
||||
engines:
|
||||
- name: google
|
||||
tokens: ['$ecretValue']
|

- name: duckduckgo

tokens: ['$ecretValue']
