I didn't know that duckduckgo.com was working with yahoo to get search results. I thought that they had their own unique search engine! Apparently duckduckgo uses yahoo's engine to provide search results, while maintaining privacy. Both DDG & yahoo claim to not use information to identify users.

#duckduckgo #yahoo
Hmm...
- clacke repeated this.

@solariiknight DDG is a metasearch engine. So it uses other search engines and systems to gather the results, including from places like Microsoft Bing.
-
@solariiknight From what I remember, #duckduckgo uses many search engines, specialized and generic, and put the results together.
-
@solariiknight I believe #duckduckgo has been using both #bing and #google, possibly at the same time, in its past. I think they crawl too.
-
They've used Bing and Yandex before. My understanding was they just use the database, while the engine that uses it is their own.

@solariiknight @mk @clacke Yahoo! search _is_ Bing nowadays, isn't it? http://searchengineland.com/microsoft-yahoo-search-deal-simplified-23299 http://money.cnn.com/2013/05/10/technology/yahoo-microsoft/index.html

@mmn @mk @solariiknight Right, I had forgotten about that, or mixed it up. That prompts the question what #duckduckgo is really getting.

@mmn @clacke @solariiknight No, not exactly. Yahoo! is not Bing, Yahoo! uses "technology" from Bing. And Bing can use Yahoo! "technology". But all this talk of "technology" is too vague. A "search engine" is many parts together, and a search engine "powered by" (parts of) another is nothing new (remember Excite? or AltaVista?). Possible "parts" are: gathering (which itself is two parts: discovery - finding new documents to investigate - and indexing - analysing documents and providing data for the database); then there's the database itself, specifically, what (meta)data is stored, and what indexes there are to that stored data. 1/2

@mmn @clacke @solariiknight Then there is querying: the part that takes a user query and tries to find content from the database that is relevant for that query. Finally there is presentation: how those relevant results get presented (and first ordered, filtered or enriched). So if Yahoo! is using Bing "technology" which part or parts is it actualy using? (Search engines "powered by" another often had only the database - so they didn't do the gathering parts - but created their own queries and presentation.) Apparently Yahoo! still has and uses some of their own "technology" and now DuckDuckGo is using some of _that_ technology. Which means??? More vagueness that doesn't really mean much at all. More, and better, data needed! 2/2
