This search example demonstrates the power of our distributed search feature. As the title suggests, it gives the user a "one-stop" searching capability, where you can search all of ETDEWEB as well as up to six additional sources, which represent over 50 million pages of R&D output. For the most part, these are energy-focused sources, such as the Danish Energy R&D projects, IEA's information center, and the French Petroleum Institute. Some are very broad and include multiple scientific disciplines, such as CORDIS (the EU's R&D database), Science.gov, and Science Conferences. The default option is to search all of these sources, but you can also uncheck certain boxes if you don't want to search a particular source. This sample search uses the term "low-energy buildings."
