Lexxe is an Internet search engine that uses natural language processing for queries. Searches can be made with questions, such as "How old is Wikipedia?", as well as keywords and phrases.

When it comes to facts, Lexxe is quite effective, but when asking more unusual questions it gives surprising answers; for example, 'How long is a piece of string?', a famously ambiguous question, as of January 24, 2010, returns the answer of '70 Cm'.

Lexxe was founded in 2005 by Dr. Hong Liang Qiao, an Australian technology expert of Chinese descent. As far as this is a new search engine it needs much improvement in natural language analysis, for example when you ask "how old is barack obama?" it returns something strange.
