Objectives: The objectives of the study were: to provide an overview of approaches to methodological search ﬁlter development; to identify and critically review the stages of methodological search ﬁlter development; to devise a search ﬁlter appraisal checklist based on the review. Methods: An iterative approach to searching was employed utilizing health and library databases, the world wide web and citation searching. Further systematic methods included hand searching of key journals in the ﬁeld of search ﬁlter development, contacting known experts in the ﬁeld and scanning reference lists of relevant papers to identify additional studies. Altogether, 51 potentially relevant papers were found, of which 20 met the inclusion criteria. Results: Four stages of search ﬁlter development were identiﬁed from the literature (search term selection, identiﬁcation of a gold standard, evaluation and validation). Variations in the methods used to approach these four stages were identiﬁed, most importantly in the extent to which search ﬁlters are tested and validated. Conclusion: Awareness of the process and limitations involved in search ﬁlter development is essential to make an informed decision on the applicability and validity of search ﬁlters. The ﬁndings of this review indicate a considerable agenda for future research, in particular, to improve the quality of reporting of search ﬁlters and to inform users on their use and application. Based on the review, guidance in the appraisal process of search ﬁlters is given in the form of a checklist.
