A metasearch engine is a search engine that searches multiple other search engines simultaneously and combines the results.
Locate evidence-based sources using a metasearch engine:
TRIP (Turning Research Into Practice) Database performs a simple search of more than 75 databases, including CDSR Abstracts, NGC, Bandolier, Evidence-Based Medicine, DARE, POEMs, etc. for access to evidence-based material as well as articles from peer-reviewed journals.
Simultaneously searches for studies (original studies and systematic reviews) and practice guidelines from PubMed, National Guideline Clearinghouse, and DARE and merged into one list sorted by year of publication.
