Across all categories, Searx can fetch search results from about 82 different engines. This includes major search engines and site-specific searches like Bing, Google, Reddit, Wikipedia, Yahoo, and Yandex.21 The engines used for each search category can be set via a "preferences" interface, and these settings will be saved in a cookie in the user's web browser, rather than on the server side, since for privacy reasons, Searx does not implement a user login model. Other settings such as the search interface language and the search results language (over 20 languages are available) can be set the same way.22
In addition to the preferences cookie, it is possible on each query to modify the engines used, search categories selected, and/or languages to search in by specifying one or more of the following textual search operators before the search keywords.23
The ! and ? operators can be specified more than once to select multiple categories or engines, for example !google !deviantart ?images :japanese cow.
Any user may run their own instance of Searx,24 which can be done to maximize privacy, avoid congestion on public instances, preserve customized settings (even if browser cookies are cleared), allow auditing of the source code being run, and more.25 Users may include their Searx instances on the editable list of all public instances, or keep them private.2627 It is also possible to add custom search engines to a self-hosted instance that are not available on the public instances.28 In 2019, Google has begun to block some self-hosted instances. This included some of the IP addresses used by searx.me from queries that result in a google (unexpected crash: CAPTCHA required) error.29 In response, some instances have been modified to silently skip trying to search with Google even when it's the only engine specified.3031
Main article: SearXNG
In the middle of 2021, some contributors of SearX forked the repo to SearXNG with a view to provide faster debugging and fixes of engine errors.32 SearXNG is for users that need a faster upstream development time with fewer bugs.3334 User theme, engine reliability and anonymous metrics are the most notable changes in SearXNG.35
