Search filters are a supplement to filters in databases. In some databases they can be insufficient or not containing what users might expect.
A search filter is a search string which can capture specific study types or specific topics.
Be aware of the fact that the use of these search filters may result in excluding relevant studies (Cooper, Varley-Campbell & Carter, 2019;. Leeflang, Rutjes, Reitsma & Bossuyt, 2006). Therefore, it is advisible to evaluate the filters before using them (Glanville et al., 2008).
Pay attention on factors such as sensitivity and precision when choosing a search filter (Beale et al., 2014).
We recommend using the search filters from the websites below.
