Jimmy Wales, the founder of Wikipedia, has said that just as internet users can contribute to articles on an open-source encyclopedia, so too will they be able to play a hand in the way the web is searched.Mr Wales said that his open-source search engine, which will let users influence the ranking of search results, should be released by the end of the year. The engine will also allow users’ computers to help crawl the hundreds of millions of pages on the web, indexing the content of each.
