Exalead has announced that it has indexed more than 4 billion Web pages. The innovative European search engine has recently consolidated its data center and implemented powerful 64-bit technology. This way Exalead hopes to double the index to eight billion Web pages by July.

Exalead is part of the Quaero initiative, the European search engine initiative claimed by French president Jaques Chirac to be the next Google.
