The current PubMed CAM filter has several non-specific search terms that contribute to the lack of specificity of search output and that identify some irrelevant studies as "CAM", such as plant-derived compounds in chemotherapy [ 20].
What he is excited about, though, is marrying the brand advertising of video with the specificity of search.
We also discussed clear ways that search could be improved such as the specificity of search and adding in time windows to limit the possible results.
In addition, Verbeek J et al have studied the sensitivity and specificity of search terms in identifying Occupational Health intervention studies [ 20].
The combination of MeSH terms and subheadings can not only facilitate the sensitivity and specificity of search, but also indicate the research contents and the relationship between papers [ 12- 14].
We then increased specificity of the search using search filters for systematic reviews or meta-analyses [ 10]. "Systematic review" or "meta-analysis" was used for all Korean databases, and "meta bunseok," "chegyejeok munheon," or "chegyejeok munheon gochal" was used in the searchable Korean databases.
To have an initial estimation of the amount of sensibility and specificity of our search, an initial test search was made in WoK with the key words and synonyms for 'psychological resilience'naturalral disasters' and 'indicator' (Additional file 1: Table S1).
The search filter acts as an optimized substitute for topic-specific terms required to increase the sensitivity and specificity of the search and eliminates the need to enter these glomerular disease terms and synonyms in the search query (e.g., nephropathy, glomerulopathy, glomerulonephritis).
There is a need for further research to see whether our findings apply to searching for epidemiological reviews of other diseases, and on measuring the sensitivity and specificity of various search filters to retrieve epidemiological studies in MEDLINE and Embase.
These tools are smart enough to get around the classic search engine failing of excessive specificity: searching for "dog" and missing all the articles that have only "canine" in them.
