List of search engines

List of search engines:
• bing.com
• duckduckgo.com
• google.com
• yahoo.com
• yandex.com

All of the above search engines have a way for you to submit a website to them, except for duckduckgo.com, which gets sites without them having to be submitted.

If you know a search engine in English that's worth using that isn't listed above, please mention it, unless it has fowl language or other inappropriate things on the site itself. The search engine need not be popular, as long as its useful.
