Umfassende Literaturrecherchen – ein Kurzüberblick.

A comprehensive literature search (CLS) describes a complex search with the aim to identify as many studies as possible to answer an underlying research question of a systematic review. However, concrete recommendations or a definition of the CLS are not available. The present article introduces a framework of the CLS, presents the associated challenges and points to methodological implications as well as potential future research topics. [ABSTRACT FROM AUTHOR]
