This section should detail how the reviewers searched for relevant papers. The databases that were searched must be listed along with the search dates. The detailed search strategies for all of the major databases and other sources searched should be appended to the review. The documentation of search strategies is a key element of the scientific validity of a systematic review. It enables readers to look at and evaluate the steps taken, decisions made to consider the comprehensiveness and exhaustiveness of the search strategy for each included database. A JBI review should consider papers published in both commercial (e.g. PubMed, Cochrane, JBI Library etc.) and in non-commercially operated databases (grey literature).
Each electronic database is likely to use a different system for indexing key words within their search engines. Hence the search strategy will be tailored to each particular database. These variations are important and need to be captured and included in the systematic review repo
