Comprehensive Lists of Search Filters

Search Filters

Search filters are standardized strategies that help identify higher quality literature within many of the medical databases. They are very useful for narrowing a search to high quality study designs but can also be used for other topics or age groups.

To incorporate a search filter into a search strategy, use AND to combine the final set of subject search with the final set of the filter.
