Yahoo hasn't had its own search engine for years. In 2010, they became essentially a frontend for Bing. In a later 2015 deal they switched the backend to using Google.

Duckduckgo is a metasearch engine, technically, but mostly it delegates to Bing.

As far as I can tell, there are only two and a half real search engines that still exist: Bing, Google, and Wolfram Alpha. (I count Alpha as a half because it's not really what most people are looking for.) I'm curious if anyone else knows of other real search engines still in existence.

Yahoo still uses Bing for majority of their searches. https://arstechnica.com/information-technology/2015/04/micro...

Check the date on that again; it doesn't contradict the parent comment.

I just tried hotbot and it seems to be better for programming-related questions than duckduckgo.

I wonder if they use mostly Google for the backend.

Baidu, Yandex, Naver, probably quite a few others.

What percentage of traffic comes from Bing though?

[hawkice]

Woah woah woah Duckduckgo delegates to Bing? If many/most searches are unique that means they can't live up to their privacy statements.

[zaptheimpaler]

If they hide the users IP, HTTP headers etc. and proxy searches to Bing through their own servers it would be anonymous.

IIRC DDG delegates the crawling to Bing, but does the actual searching itself.

Another half (read: limited-scope) search engine that springs to mind is Shodan.

Did Yahoo ever have its own search engine, technically? In the early web it was a directory maintained by humans, which made sense at a time when the total number of pages in existence on any given subject was no more than a few hundred; I thought that when that era passed they went straight into licensing other search engines' results.

I worked at Google on search indexing at the time Yahoo switched from their own search engine to using Bing. At the time, by most of Google's own search metrics, Yahoo had a product superior to Bing. If Bing had been spun off as a separate company, or otherwise hadn't had access to Microsoft's deep pockets and default IE search status, it's likely Yahoo would have fared better.

[Endy]

Nope, they had a spider-crawler and a full engine along with the human-curated Directory.

The sequence was: Yahoo Directory -> Yahoo showing Google results -> Yahoo builds their own search engine -> Yahoo uses bing
