If you answered yes, most probably your first trial was to conduct a text-based search using the database query. However, it might work, but the database’s ability to provide relevancy is either non-existent or a bolted-on afterthought, and the relevancy ranking of results coming out of a database won’t be satisfactory.
Additionally, if we added the performance to the equation when you have large volumes of text data, RDBMS will be quite slow and provide poor user experience.
