TIP: Using quotation marks prevents the database or search engine from searching each word individually, potentially retrieving irrelevant articles. However, you do not want to include too many words, as it could cause the search to become so narrow it omits relevant articles that may have the words near each other but not next to each other.
TIP: PubMed uses automatic term mapping (ATM) to seamlessly search and retrieve all possible synonym and MeSH entries of a searched word/term. If you are sure you only want results containing a specific term then use quotation marks as it turns off ATM.
