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 SearXNG reactivity (the result page may take the time specified in the timeout to load). Can be override by timeout in the engines:.
useragent_suffix :: Suffix to add when an engine’s User-Agent is set via searxng_useragent(). Contact info here may be useful to avoid an engine blocking you.

pool_connections :: Maximum number of concurrent connections. The default is 100. See max_clients Pool limit configuration.

proxies :

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

HTTP, HTTPS, SOCKS4, SOCKS5 and SOCKS5h proxies are supported (http://, https://, socks4://, socks5://, socks5h://). You should use socks5h:// when using Tor so hostnames are resolved by the proxy.

source_ips :

If you use multiple network interfaces, define from which IP the requests must 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, SearXNG uses an different proxy and source ip.

enable_http2 :

Enable by default (HTTP/2). Set to false to force HTTP/1.1. HTTP/3 is opt-in per engine (enable_http3).

verify:$SSL_CERT_FILE, $SSL_CERT_DIR

HTTPS verification uses the OS’s trust store by default. Set a path to use a custom CA file.

In addition to verify, SearXNG supports the $SSL_CERT_FILE (for a file) and $SSL_CERT_DIR (for a directory) OpenSSL variables.

max_redirects :

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

using_tor_proxy :

Using tor proxy (true) or not (false) for all engines. The default is false and can be overwritten in the engines:
