We aim to provide search strategies which help researchers find evidence, and review authors build their search strategie. Please note that the suggested search strings are not validated, not exhaustive, and hence should merely serve as examples to support professionals and researchers in building their search strategies.

Institutions providing search strategies and search filters:

Cochrane Work provides search strategies related to occupational health, providing filters for both professionals and researchers.

HIRU (Mc Master's Health Information Research Unit) offers search strategies for researchers covering topics like prognostic, diagnostic, causation (etiology) and economics.

SIGN (Scottish Intercollegiate Guidelines Network) uses search filters developed in-house or are created by other research organisations and adapted to meet SIGN information needs. SIGN's filters may provide less sensitive searches than used by other systematic reviewers such as Cochrane, but enable the retrieval of medical studies that are most likely to match SIGN's methodological criteria.

HLWIKI International provides a collection of key websites and filters for search strategies, such as filters for quantitative studies, systematic reviews, and links to other libraries and universities search filters.

The ISSG (InterTASC Information Specialists' Sub-Group) Search Filter Resource is a collaborative venture to identify, assess and test search filters designed to retrieve research by study design or focus. The Search Filters Resource aims to provide easy access to published and unpublished search filters.
