Undergraduate research assignments at Northwestern State University College of Nursing allow the document types. In Pubmed My profile, you can specify only these types of documents. Specifying these document types omits over 50 other document types. This ensures you retrieve only those types of articles acceptable to your professors.
After setting up your NCBI Account, you specify document types. When you sign in to PubMed NCBI, your search results are automatically filtered to these document types. This is a screenshot of your MyNCBI Dashboard document filter types:
You may also set up other filters to simply your search results:
Limit the number of search results:
Enter the author’s last name and initials without punctuation in the search box, and click Search.
If you only know the author’s last name, use the author search field tag [au], e.g., brody[au].
Names entered using either the lastname+initials format (e.g., smith ja) or the full name format (john a smith) and no search tag are searched as authors as well as collaborators, if they exist in PubMed.
Enter a full author name in natural or inverted order, e.g., julia s wong or wong julia s.
Omit periods after initials and put all suffixes at the end, e.g., vollmer charles jr
Initials and suffixes are not required. If you include a middle initial or suffix, you will only retrieve citations for articles that were published using the middle initial or suffix.

Enter one of the following in the search box:

A list of journals included in PubMed is available by FTP.
Click and drag the sliders on the Results by Year timeline to change the date range for your search.
Note: The Results by Year timeline counts all publication dates for a citation as supplied by the publisher, e.g., print and electronic publication dates. These dates may span more than one year; for example, an article that was published online in November 2018 and published in a print issue in January 2019. This means the sum of results represented in the timeline may differ from the search results count.
Enter dates using the format yyyy/mm/dd [date field]. The month and day are optional.
Use a Boolean operator when combining a date with other search terms.
Use the Boolean operator AND to limit your search to a specific publication date.cancer AND 2020/06/01[dp]
The available date fields are:
Enter date ranges using a colon (:) between each date followed by a [date field].
Use a Boolean operator when combining a date range with other search terms.
Use the Boolean operator AND to limit your search to a date range.heart disease AND 2019/01/01:2019/12/01[dp]
Comprehensive searches for a full year should be entered as 2000:2000[dp] rather than 2000[dp] to retrieve citations with a different print and electronic year of publication.
Date range searching includes both print and electronic dates of publication.
Use the following format to search for a relative date range:
where X is the number of days, months or years immediately preceding today’s date and [date field] is the date field tag: [dp], [edat] or [crdt].
The relative date range search for publication dates will also include citations with publication dates after today's date; therefore, citations with publication dates in the future will be included in the results.
PubMed does not perform adjacency searching. However, many phrases are recognized by the subject translation table used in PubMed's Automatic Term Mapping (ATM). For example, if you enter fever of unknown origin, PubMed recognizes this phrase as a MeSH Term.
You can bypass ATM and search for a specific phrase using the following formats:
Phrases may appear in a PubMed record but not be in the phrase index. To browse indexed phrases, use the Show Index feature included in the Advanced Search Builder: select a search field, enter the beginning of a phrase, and then click Show Index.
When you enter search terms as a phrase, PubMed will not perform automatic term mapping that includes the MeSH term and any specific terms indented under that term in the MeSH hierarchy. For example, "health planning" will include citations that are indexed to the MeSH term, Health Planning, but will not include the more specific terms, e.g., Health Care Rationing, Health Care Reform, Health Plan Implementation, that are included in the automatic MeSH mapping.
To search for all terms that begin with a word, enter the word followed by an asterisk (*): the wildcard character.
To search for a bound phrase including a truncated term, use the following formats:
At least four characters must be provided in the truncated term.
The truncated term must be the last word in the phrase.
Truncation turns off automatic term mapping and the process that includes the MeSH term and any specific terms indented under that term in the MeSH hierarchy. For example, heart attack* will not map to the MeSH term Myocardial Infarction or include any of the more specific terms, e.g., Myocardial Stunning; Shock, Cardiogenic.
PubMed applies an AND operator between concepts, e.g., "vitamin c common cold" is translated as vitamin c AND common cold. Enter Boolean operators in uppercase characters to combine or exclude search terms:
PubMed processes searches in a left-to-right sequence. Use parentheses to "nest" concepts that should be processed as a unit and then incorporated into the overall search.
Boolean operators must be used when combining tagged search terms as follows: search term [tag] BOOLEAN OPERATOR search term [tag]. See Search Field descriptions and tags.
