Yahoo! Inc., has unveiled a new paid search product, where customers will be able to buy specialized documents that are not generally available on consumer search engines. The service, called Yahoo
Premium Document Search, is being offered in partnership with Divine Inc, a Chicago company, which on Tuesday acquired the Northern Light search engine. Northern Light, based in Cambridge, Mass,
recently announced it was closing its free consumer search engine and focusing on specialized search services. The company's search product features an assortment of documents like trade publication
articles, financial analyst research reports and medical journals that are more in-depth than a lot of free web content. Yahoo said that under the new fee structure, consumers will be able to pay for
individual documents, usually at a cost of $1 to $4 apiece, or to pay $4.95 upfront for access to 50 documents.
