Exalead (pronounced /ɛɡˈzæliːd/ in English) is a French search engine involved in the Quaero project.

Exalead provides thumbnail previews of the target pages along with the results, and allows advanced refining on the results page (language, geographic location, file type, categories) but also further data refinement, such as rich content (audio, video, RSS) and related terms, allowing users to browse the web by serendipity.

[edit] Exalead

The company is a société anonyme based in Paris^[1] and founded in 2000 by François Bourdoncle. Its name comes from the association between

the prefix exa which means 10¹⁸ (used as a generic term for size, to imply large coverage of pages)
and the verb lead (as the customer is led through the search options)

Exalead tries to integrate research functions in one piece of software, combining Internet, desktop and enterprise functionality.

Exalead employs approximately 70 people in 6 countries (Paris in France, Milano in Italy, Weinheim in Germany, Glasgow in UK and New York in the United States).
