Why we decided to use MeSH terms:

Harnessing the might of MeSH terms in your PubMed quest can be transformative. It streamlines the often daunting task of ferreting out relevant articles with remarkable ease and precision. To illustrate this power, consider a PubMed search for the MeSH term “fermented foods.” What unfolds is PubMed’s impressive ability to summon forth articles seamlessly, even if the words “fermented” and “foods” remain absent from the article’s title or abstract.
