Exalead [eg'zæli:d] is a French search engine involved in the Quaero project, introducing new search techniques.

Exalead provides thumbnails previews of the target pages along with results, and allows usual advanced refining on the results page (language, geographic location, file type, categories) but also innovative refining 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 and founded in 2000 by Francois 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 60 people in 3 countries (Paris in France, Milano in Italy and New York and San Francisco in the United States of America).
