The most ambitious application of EXTRAKT is the Lexiquo Portal:

www.extraktsearch.de

LexiQuo is a meta-search engine which sends search requests to different search engines (Yahoo, Bing, Exalead and Wikipedia).

The original terms of the request are analyzed and word variants as well as synonyms and translations are added to the request. By a single click, these variants can be added to the original request.

LexiQuo has a tri-lingual interface,  but is able to analyze requests in 4 languages:

German, French, English, Italian and Spanish are supported.
