PubMed Central works best by building search strings.
Add "quotation marks" around phrases. This tells the database to treat the phrase as one term (rather than searching for each word individually).
Truncation is a method that allows you to search for all variations of a word. Type the root of the word followed by an asterisk (*). For example:
will provide results for multiple keywords such as
nurse, nurses, nursing
Use AND, OR, NOT (in uppercase characters) to combine or exclude search terms:
AND = will only show results that include BOTH terms
OR = will show results if they have at least one of the terms
NOT = will exclude results that use that term
To group terms together, add (parentheses). For example:
"cardiac nursing" AND ("blood pressure" OR "heart palpitations") NOT "pediatric"
This search would include results about cardiac nursing (excluding pediatric nursing) that discuss blood pressure, heart palpitations, or both.

Limit your search results by:
Dates or date ranges can be added to your search string. For dates, use the format YYYY/MM/DD[pubdate]. Month and day are optional. For example:
"2020/03/15[pubdate]" or "2020/03[pubdate]" or "2020[pubdate]"
For date ranges, put a colon (:) between each date. You can also search for the last number of days, months, or years. For example:
"2020:2023[pubdate]" or "last 3 years[pubdate]"
Dates or date ranges can also be added via a filter in the search results.
Use the author's full name, last name, or last name with initials (no punctuation) as a search term. You can also add the author search field tag [au]. For example, any of these options should provide sources by John Smith:
