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.

.. _PySocks: https://pypi.org/project/PySocks/

Number of seconds to keep a connection in the pool. By default 5.0 seconds.

``proxies`` :
|
||||
Define one or more proxies you wish to use, see `requests proxies`_.
|
||||
Define one or more proxies you wish to use, see `httpx proxies`_.
|
||||
If there are more than one proxy for one protocol (http, https),
|
||||
requests to the engines are distributed in a round-robin fashion.
|
||||
|
||||
- Proxy: `see <https://2.python-requests.org/en/latest/user/advanced/#proxies>`__.
|
||||
- SOCKS proxies are also supported: `see <https://2.python-requests.org/en/latest/user/advanced/#socks>`__

``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.

||||
be made. Example:
|
||||
|
||||
* ``0.0.0.0`` any local IPv4 address.
|
||||
* ``::`` any local IPv6 address.
|
||||
* ``192.168.0.1``
|
||||
* ``[ 192.168.0.1, 192.168.0.2 ]`` these two specific IP addresses
|
||||
* ``fe80::60a2:1691:e5a2:ee1f``
|
||||
* ``fe80::60a2:1691:e5a2:ee1f/126`` all IP addresses in this network.
|
||||
* ``[ 192.168.0.1, fe80::/126 ]``
|
||||
|
||||
``retries`` :
|
||||
Number of retry in case of an HTTP error.
|
||||
On each retry, searx uses an different proxy and source ip.
|
||||
|
||||
``retry_on_http_error`` :
|
||||
Retry request on some HTTP status code.
|
||||
|
||||
Example:
|
||||
|
||||
* ``true`` : on HTTP status code between 400 and 599.
|
||||
* ``403`` : on HTTP status code 403.
|

* ``[403, 429]``: on HTTP status code 403 and 429.

``enable_http2`` :
|
||||
Enable by default. Set to ``False`` to disable HTTP/2.

``max_redirects`` :

30 by default. Maximum redirect before it is an error.
