View AbstractPurpose: The present study evaluates the retrieval performance of three search
engines, i.e., Google, Yahoo, and Bing, using four evaluation parameters: precision,
recall, duplicate links, and comprehensiveness in nursing.
Methodology: The three popular search engines in health sciences, i.e., Google,
Yahoo, and Bing, were selected for evaluation. Clarivate Analytics’ Web of Science
was used to extract the queries in the nursing field.
Findings: Bing achieves the highest total mean precision. However, Google has the
highest overall mean relative recall and number of results. The overall mean
precision, duplicate links, and number of hits of select search engines are highest
for three-word queries. However, overall relative recall is equal for all the query
intents. Furthermore, Yahoo retrieves a maximum number of duplicate links.
Research implications: The study will be helpful for researchers and healthcare
professionals to understand the retrieval efficiency of Google, Yahoo, and Bing in
seeking answers to queries in the field of nursing. Search engines’ retrieval
effectiveness determines the users’ precise health decision-making capability. The
study offers the best platform for executing different query structures across select
search engines to achieve desired results without losing key results. The results may
also prove helpful to search engine companies for improving the retrieval efficiency
of their services in the area of health sciences in general and nursing in particular.
Originality: Several performance schemes have been employed to evaluate the
retrieval effectiveness of search engines. Nevertheless, users may not know which
search engine is best for retrieving relevant information from the Internet in
nursing. The study highlights the retrieval effectiveness of generally used search
engines in nursing.
