In brief

A search strategy is a structured set of key phrases that are used to search a database. In order to return reliable results, the search strategy integrates the important components of your research paper question.

Introduction

Developing a search strategy for a systematic review involves several steps:

Identify the research question: Start by clearly defining the research question and identifying the key concepts and terms that are relevant to the question.

Select the databases: Determine which databases are most appropriate for the research question. Common databases used in systematic reviews include MEDLINE, EMBASE, Cochrane Library, PsycINFO, and CINAHL.

Develop the search terms: Identify relevant terms and synonyms for the key concepts in the research question. These terms should be specific and not too broad or too narrow. Consider using MeSH terms or other controlled vocabulary terms.

Combine the search terms: Use Boolean operators (AND, OR, NOT) to combine the search terms, and use truncation or wildcards to capture different forms of the search terms. Be sure to account for variations in spelling, pluralization, and word order.

Run the search: Run the search strategy in each database and record the number of hits.

Screen the results: Screen the titles and abstracts of the search results to identify potentially relevant studies. Exclude studies that clearly do not meet the inclusion criteria.

Full-text articles: Obtain the full text of potentially relevant studies and screen them to determine eligibility for inclusion in the systematic review.

Update the search: Repeat the search periodically to identify any new studies published since the initial search.

It is essential to document the search strategy in detail, including the search terms used, the databases searched, and the number of hits at each stage. This information should be reported in the systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

KEEPING A RECORD OF YOUR SEARCH ACTIVITY

To maintain track of productive search keywords or to assist others in following your steps and obtaining the same results, good search techniques may require keeping a search diary or document recording your search activity.

This record could be a document, table or spreadsheet with the following:

The names of the sources you searched for and the service provider you used to access them, such as Web of Science (Thomson Reuters) or Medline (Ovid). Include any more literary materials you consulted as well.

The search techniques you used to look for information from various sources (such as Medline and Web of Science) can be included as an appendix to your work. This offers more information on the following:

Using a keyword or subject title as part of your search
which search keywords (words and phrases) you entered

any search strategies you used (such as adjacency, truncation, etc.)
How you (AND/OR) combined your search keywords? More information about boolean searching may be found in the database help section.

The quantity of search results from every source and technique. This may be the proof you require to establish a gap in the literature and to support the validity of your research topic.
