For the search, I searched: (evidence or topic) and based and (librarians or library). When I used the () around (evidence or topic) I didn't have any hits in Academic Search Complete. When I removed the () around the terms, I received hits. I decided to narrow it a little more so I added medicine to the search terms. I think the building block (BB) strategy helped me to find information. However, I think it also returns many items that are not really related to the information you are looking for. I do think the BB strategy helps you to narrow down your topic to what you are truly looking for though.
