Presenting a search strategy

Have you done a structured search related to a literature review or other work? Do you need to present how you found the articles you selected? Are you thinking about how you can present articles that you have found alongside the search, for example via a reference list to another article? Here you can see what information should be included in a search strategy presentation, and some examples of what it might look like.

What should be included in a search strategy presentation?

How can you present your search strategy?

  • Strive to be as transparent as possible, it should preferably be possible for someone else to repeat your search and get the same result.
  • In the methods section you describe how you did: if you did test searches, how you found search words, if you searched with both free-text words and controlled subject headings.
  • In the method section, you can also describe and report articles that you have found in other ways than via the database search, for example if you have found articles via a reference list to another article or by manual search.
  • The complete search strategy is usually also presented in table form. The table can be added as an appendix to the work.
  • In order for you to be able to present your search strategy, it is important that you save the search you have made, in some way. A tip is to cut and paste from the database's "Search history".
  • It is also possible to create an account in the databases to save searches.

What should a search strategy presentation contain?

  • The name of the database
  • The date you did the search
  • Which search terms you have used
  • How you searched (quotes, especially fields, truncations, etc.)
  • How you have combined your search terms
  • If you have used any filter, or restriction (language, year, etc.)

Example of text in the methods section

The searches were conducted during June 2018 in the databases CINAHL, Web of Science and PubMed.

The Mesh terms identified for the PubMed search were adapted to corresponding terms in CINAHL. Every individual search term was supplemented with relevant free text terms. When appropriate, the free text terms have been truncated in order to include alternative word endings.

The search result was limited to articles that were written in English as well as articles published during the last ten years. The full search strategy is included as an appendix.

The database searches were complemented with manual review of the reference lists of relevant articles, which resulted in a few additional articles included in the study.

Examples from different databases

In the tables below we present searches in three different databases. In all databases we have used the topic "Patients' experience of day surgery".

The examples we show below are intended as general support. If there are instructions for your own program, you should use these in the first place.
