Combine keywords using "AND" or "OR" - "AND" finds the intersection of the concepts. "OR" finds any one of the concepts.
TIP: Searches can be combined or used in subsequent searches using Advanced - Search History.
One way to limit your search to particular fields is by using field tags, such as [ti] to search a title word, [au] to search an author name word, [ta] to search a journal title word, etc.
Example: "food desert"[ti] searches for this phrase in the article title.
A complete list of all PubMed field tags as well as description of each is available from PubMed Help
