# Search syntax

SearXNG comes with a search syntax by with you can modify the categories, engines, languages and more. See the `preferences` for the list of engines, categories and languages.

## `!` select engine and category

To set category and/or engine names use a `!` prefix. To give a few examples:

- search in Wikipedia for paris

  - `!wp paris`

  - `!wikipedia paris`

- search in category map for paris

  - `!map paris`

- image search

  - `!images Wau Holland`

Abbreviations of the engines and languages are also accepted. Engine/category modifiers are chain able and inclusive. E.g. with `!map !ddg !wp paris` search in map category and DuckDuckGo and Wikipedia for paris.

## `:` select language

To select language filter use a `:` prefix. To give an example:

- search Wikipedia by a custom language

  - `:fr !wp Wau Holland`

## `!!<bang>` external bangs

SearXNG supports the external bangs from DuckDuckGo. To directly jump to a external search page use the `!!` prefix. To give an example:

- search Wikipedia by a custom language

  - `!!wfr Wau Holland`

Please note, your search will be performed directly in the external search engine, SearXNG cannot protect your privacy on this.

## `!!` automatic redirect

When mentioning `!!` within the search query (separated by spaces), you will automatically be redirected to the first result. This behavior is comparable to the “Feeling Lucky” feature from DuckDuckGo. To give an example:

- search for a query and get redirected to the first result

  - `!! Wau Holland`

Please keep in mind that the result you are being redirected to can’t become verified for being trustworthy, SearXNG cannot protect your personal privacy when using this feature. Use it at your own risk.

## Special Queries

In the `preferences` page you find keywords for special queries. To give a few examples:

- generate a random UUID

  - `random uuid`

- find the average

  - `avg 123 548 2.04 24.2`

- show user agent of your browser (needs to be activated)

  - `user-agent`

- convert strings to different hash digests (needs to be activated)

  - `md5 lorem ipsum`

  - `sha512 lorem ipsum`
