Custom search engines allow you to search any website from the address bar by typing a keyword, tab (or space in Firefox), and then your search query. These strings can also be used in programs and scripts.

Note: For security purposes, only https URLs will be included in this repo.

Read the guide for Firefox or the guide for Chrome.

Note: The %s in the strings should be removed for Firefox.

The custom-search-engines.csv file is a catalog presenting the available search engines, as well as their category, a description and a proposal of keyword to use them within the search bar.

You will find below some examples of custom search engines. These entries will be updated in the same way as the global catalog.
