About Search Filters

Apply a pre-made MEDLINE search strategy or "search filter" to your search to save you time. Filters are optimised search strategies designed by search experts. They aid effective searching by providing a more precise and relevant set of results.

There are two search filter types:

  1. Study design/methodology filters
  2. Topic filters

A search filter is used in combination with search terms that describe your topic of interest. Identify the main concepts and their keywords in your topic or research question before you apply a search filter.

Follow the steps in this guide to learn how to combine your chosen MEDLINE search filter with your identified search terms.
