The 2 minute video below shows starting a keyword PubMed search from the LHL homepage search box and finding the full text article.
PubMed indexes articles using controlled vocabulary called Medical Subject Headings (MeSH). This enables all articles about a certain subject to be retrieved, even if different terms for the concept are used in the article, such as myocardial infarction or heart attack.
The PubMed search engine uses "automatic term mapping" to map your search to the appropriate MeSH term. You can display the MeSH terms for a citation in Abstract View as shown below:
Click on "MeSH terms" to display terms.
To start searching, just enter your search terms in the PubMed search box. You can check how your search was mapped in the "Details" box on the right dashboard in the result set. Then focus your search.
