How Do We Conduct A Thorough Literature Search For A Systematic Review?

In the case of a systematic review, searching for literature is part of the research methodology. The search will usually try to capture as much literature as possible, while inclusion and exclusion criteria will be used to reduce the amount of it. Documentation of the search will make the review work replicable for other researchers. The guidance documents summarise ‘how to’ search bibliographic databases in detail and this guidance is further contextualised above in terms of developing the search strategy. The host of the database (e.g. OVID or ProQuest) has been shown to alter the search returns offered. Younger and Boddy report differing search returns from the same database but where the ‘host’ was different .

Knowing where to search for studies was noted as important in the guidance, with no agreement as to the appropriate number of databases to be searched .

It also forces you to figure out how these sources are relevant to your goals as a researcher, giving you a more informative and educated sense of where your research falls in the academic community. You’ll need to specify your topic and figure out what and where to search. From there, do extensive research and find a variety of sources. Write up summaries of the sources, while making connections between them, and then proofread your search and look for any places where additional research may be necessary. You will want to identify Highly Cited research as a group of papers. This group will help guide your analysis of the future of the field and opportunities for future research.

Without an explicit model, research in the process of systematic literature searching will remain immature and potentially uneven, and the development of shared information models will be assumed but never articulated. In order to conduct your search appropriately, some background reading is necessary. Read some other literature reviews of projects related to your topic. You should read a few peer-reviewed research papers, which you can find at most academic libraries, on your subject. Keep track of what names and authors crop up again and again in these sources so you get a sense of the big names in your field.

In addition, Google Scholar finds articles cited by other relevant articles produced in the search. Google Scholar alone has not been shown to retrieve more literature than other traditional databases discussed in this article and therefore should be used in addition to other sources . Before conducting a comprehensive literature search, a scoping search of the literature using just one or two databases can provide valuable information as to how much literature for a given review question already exists. A scoping search may reveal whether systematic reviews have already been undertaken for a review question. Caution should be taken, however, as systematic reviews that may appear to ask the same question may have differing inclusion and exclusion criteria for studies included in the review.

Use these relevant results to identify keywords, index terms, or subject headings that have been assigned to those items. Defining the relationships between search terms and combining them are critical steps in the search process. How terms are linked in a search strategy can significantly affect the outcome of a search. In order to create an effective and efficient search, it is worthwhile to put some time into developing a search strategy instead of simply adding any potential words into a single search field.
