Systematic review searches must be documented in sufficient detail to allow others to be able to assess the thoroughness of the search. You will need to keep track of:

• database searched, together with the platform searched via (eg. OVID Medline, Ebsco PsycINFO, CSA Sociological Abstracts)
• date each search were conducted
• Subject headings and keywords used - including whether terms were exploded, truncated, etc
• Search history, including the combination of terms
• Number of results retrieved for each search and combination
• Total number of records
• Duplicates identified
• Numbers pre-screening and post-screening

In addition, all searches conducted via handsearching must identify the source (name of journal, conference proceedings, etc), plus the years.
