port :

Port number of the searx web application if you run it directly using python searx/ Doesn’t apply to searx running on Apache or Nginx.

secret_key :

Used for cryptography purpose.

debug :

Allow a more detailed log if you run searx directly. Display detailed error messages in the browser too, so this must be deactivated in production.

request_timeout :

Global timeout of the requests made to others engines in seconds. A bigger timeout will allow to wait for answers from slow engines, but in consequence will slow searx reactivity (the result page may take the time specified in the timeout to load)

base_url :

The base URL where searx is deployed. Used to create correct inbound links.

themes_path :

Path to where the themes are located. If you didn’t develop anything, leave it blank.

default_theme :

Name of the theme you want to use by default on your searx instance.

useragent_suffix :

Suffix to the user-agent searx uses to send requests to others engines. If an engine wish to block you, a contact info here may be useful to avoid that.

image_proxy :

Allow your instance of searx of being able to proxy images. Uses memory space.

default_locale :

Searx interface language. If blank, the locale is detected by using the browser language. If it doesn’t work, or you are deploying a language specific instance of searx, a locale can be defined using an ISO language code, like fr, en, de.

proxies :

Define one or more proxies you wish to use, see requests proxies. If there are more than one proxy for one protocol (http, https), requests to the engines are distributed in a round-robin fashion.

source_ips :

If you use multiple network interfaces, define from which IP the requests must be made. This parameter is ignored when proxies is set.

locales :

Locales codes and their names. Available translations of searx interface.

name :

Name that will be used across searx to define this engine. In settings, on the result page…

engine :

Name of the python file used to handle requests and responses to and from this search engine.

shortcut :

Code used to execute bang requests (in this case using !bi or ?bi)


Part of the URL that should be stable across every request. Can be useful to use multiple sites using only one engine, or updating the site URL without touching at the code.


Define in which categories this engine will be active. Most of the time, it is defined in the code of the engine, but in a few cases it is useful, like when describing multiple search engine using the same code.


Timeout of the search with the current search engine. Be careful, it will modify the global timeout of searx.


In a few cases, using an API needs the use of a secret key. How to obtain them is described in the file.


To disable by default the engine, but not deleting it. It will allow the user to manually activate it in the settings.


If you want to use another language for a specific engine, you can define it by using the full ISO code of language and country, like fr_FR, en_US, de_DE.

weigthdefault 1

Weighting of the results of this engine.

display_error_messagesdefault True

When an engine returns an error, the message is displayed on the user interface.


A few more options are possible, but they are pretty specific to some engines, and so won’t be described here.
