About DuckDuckGo

DuckDuckGo don't track

Unlike all major search engines, DuckDuckGo does not collect or share personal information. There is no search history, personal profile or any other information about you gathered, stored, sold, used or leaked. For more information on this, you can read their privacy policy.

DuckDuckGo don't bubbling

In other search engines, search results are personalized based on your Web history and personal profile. In other words, if two people search for exactly the same thing, they won’t necessarily see the same results. Based on the personal information the search engines have on them, different customized results will be shown. DuckDuckGo does not gather such personal information and does not customize search results. So if two people search for the same thing, they’ll get the same results. For more information on this, you can read this illustrated guide.

DuckDuckGo Features

DuckDuckGo is full of features.. and it’s hard to summarize them all. So let’s have a look at a few of them.

DuckDuckGo comes with something called the !bang syntax. Using that syntax you can quickly search using other search engines…

For instance, here are a few search queries and their respective results:

Query Results
ghostbsd DuckDuckGo results for ghostbsd
 !yt ghostbsd Youtube video results for ghostbsd
 !g ghostbsd Google results for ghostbsd
 !gi ghostbsd Google image results for ghostbsd
 !bi ghostbsd Bing image results for ghostbsd

As you can see, you can use the !bang syntax to issue queries on Youtube, Google, Bing, Yahoo, and many other search engines. Of course when you’re using these other search engines, your personal information is tracked and your results are bubbled. Nonetheless it’s extremely convenient to have access to everything out there from a single search plugin. There are hundreds of engines and query types you can use with the !bang syntax. For more information on this, please read the !bang features. DuckDuckGo also features Zero-Click info sources, keyboard shortcuts, locations, calculations, conversions..etc. For a complete overview, please have a look at the DuckDuckGo features.

DuckDuckGo with Open Source

DuckDuckGo is built on Open Source. Its backend is primarily in Perl and served via nginx. It uses a number of other open source components as well, such as PostgreSQL, Solr, and memcached.

Much of DuckDuckGo source is closed, but a growing portion is open. DuckDuckGo’s community platform (not yet launched) will be completely open. And DuckDuckGo has opened interfaces to enable Open Source developers to contribute goodies, API integrations and data stores to improve the search engine for everyone on particular subsets of queries.

DuckDuckGo has pledged to give back to the Open Source community. In 2010, the search engine sent donations to nginx, FreeBSD, Tor, Clamwin, Taho-LAFS and OpenSSH. With input from the DuckDuckGo community, DuckDuckGo will contribute new donations for 2011.

DuckDuckGo signed a partnership with GhostBSD to share revenue generated by the “sponsored links” within the search results seen by GhostBSD users. By using the DuckDuckGo search plugin, you help fund GhostBSD and DuckDuckGo.

GhostBSD whit DuckDuckGo

In GhostBSD 3.0, DuckDuckGo is now the default search engine. It comes with a learning curve. You can use it easily, but you’ll need to go through a bit of reading to understand its power and how to make the most of it. Of course, if you’d rather use what you’re familiar with you can.

GhostBSD is entering the search market. Our product is free and our focus is dedicated on improving the BSD desktop. Almost all our competitors either charge for their product (Microsoft, Apple) or engage in commercial activities. Our business model needs to fund GhostBSD and give us the ability to focus entirely on the desktop to guarantee we can continue to innovate and enjoy sharing our work for free. We’re community-driven, we’re financed by our community and by its activity on the web and its interaction with advertisers. The first search engine to share with us the income generated by GhostBSD users is DuckDuckGo, and as it happens, it’s one of the most interesting engines out there.

So in GhostBSD 3.0, you have all the information you need to understand how your activity on the web and your search queries can help fund the distribution. And of course, because it’s your computer and because the main thing is your user experience and enjoyment while using GhostBSD, you have the choice to what you want to do. Whether it’s using DuckDuckGo, or adding other search engines to GhostBSD, we made it all very clear and very easy.
