Science Search Is Now More "Relevant" than Ever

San Francisco —The latest version of, launched today, deploys "DeepRank" which allows search and relevancy ranking across full text of documents, when full text is available. In addition, 4.0 adds a "refine results" option to narrow returns within a search, as well as an "e-mail results" feature so that individuals may email important science information to themselves, friends and family, or colleagues. Version 4.0 offers more ways to view search results: by title, author or date, as well as by relevancy rank or source, as in earlier versions. [ Download fact sheet (239-KB PDF).]

"Once again, has brought new features and new technology to the forefront for those who need science information quickly," said Eleanor Frierson, Deputy Director, National Agricultural Library and co-chair of the Alliance. " You get a lot of search with just one query, and your results are more relevant than ever."

Tom Lahr, Deputy Associate Chief Biologist for Information, U.S. Geological Survey, and co-chair of the Alliance, noted that Version 4.0 will help citizens find the science information they need. "Already, searches authoritative science information from 30 federal scientific databases and more than 1,800 science Web sites," said Lahr. "Now DeepRank, a more sophisticated ranking tool, will help return even more targeted results from these resources."

At, a single query can be launched across more than 50 million pages of science information and research results. allows users to search the surface Web as well as the deep Web, where traditional search engines typically cannot go. The information is free and no registration is required.
