Search filters

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 (Leeflang, Rutjes, Reitsma & Bossuyt, 2006). Therefore, it is advisible to evaluate the filters before using them (Glanville et al., 2008).
