For a routine assessment, keeping brief notes of useful terms, databases and sources may be enough.
For a dissertation, structured literature review or research project, you may need a more detailed record containing:
- the databases and search tools used
- the date each search was conducted
- the search terms or complete search strings
- filters and limits applied
- the number of results
- relevant changes made to the search
- how sources were selected or excluded
- any citation chaining or other discovery methods used
Postgraduate researchers are expected to use a rigorous and documented approach appropriate to their discipline, research question and methodology. However, not every postgraduate research project is a systematic review.
Example: a search log

Scan titles and abstracts for relevance. Test other relevant wellbeing terms and compare the results. |
Where required, also record your source-selection decisions and any citation chaining or other discovery methods. Keeping references to sources is different from keeping a record of how you searched for and selected them.
Systematic, scoping and other evidence reviews have specific methodological requirements. Searching several databases or keeping a log does not by itself make a review systematic. Follow the method required by your programme, supervisor or review protocol.
AI research assistants and literature mapping tools can provide additional routes to possible sources, but using one does not make a search comprehensive or reproducible.
