DuckDuckGo is an Internet search engine that does not track and profile its users and shows all users the same search results for a given search term. It also emphasizes getting information from the best sources rather than the most sources, generating its search results from key crowdsourced sites such as Wikipedia and from partnerships with other search engines such as Yandex, Yahoo!, Bing and WolframAlpha.
It features the use of !bangs, or commands that apply filters to searches. For example, !wes will search Wikipedia in Spanish and !rae will search the dictionary of the Real Academia Española. For a list of !bang commands, type !bang in the search window.

BabelNet 2.0 covers 50 languages and is obtained from the automatic integration of WordNet, Open Multilingual WordNet, Wikipedia and OmegaWiki.
