When searching Everything or Articles, natural language often works well.
For Books and Media, keywords or short, common phrases usually work better. Use quotation marks for an "exact phrase."
You also can search a digital object identifier (DOI) or International Standard Book Number (ISBN) for a known item.
For more complex searches like (climate change OR global warming) AND polar bears, use Advanced Search.
