This video demonstrates how to use the PubMed Advanced Search Builder,
a good way to refine your PubMed searches.
I’ll start by clicking Advanced on the PubMed homepage and selecting MeSH Terms from the
All Fields menu. When I start to type my first term, hyperglycemia, the autocomplete feature
offers possible MeSH Terms based on my entry. I’ll select hyperglycemia.
Notice that terms entered in the builder are automatically added to the box above.
I’ll add another term to my search by typing newborn on the second line. The default
Boolean operatoris AND; if desired, choose OR or NOT from the pull-down menu.
Click ‘Add to history’ to display the result count for the search thus far; this
is like using the Preview button on other advanced search pages. ‘Add to history’
also allows me to temporarily store this search for use in a subsequent searches. To permanently
store the search, click on the search number in History. You can then choose,
Save in My NCBI. If I click ‘Add’, my search is added
to the search builder.
I’ll continue to add terms by choosing MeSH Subheading in the next builder box. To see
an alphabetical list of all terms in this search field, I’ll click ‘Show index list.’
Scroll until you find the correct term and then highlight it to add it to the search
box. I’ll select drug therapy.
To clean up the page a bit, I’ll click ‘Hide index list.’ If you are ready to retrieve
your records, click ‘Search.’ If not, there are a few ways you can edit the search.
You can continue to add terms, you can use the ‘-’ icon to remove a specific term,
or use the Clear link to completey start over. If you want to manually change the Search
Builder field, use Edit. Note that once you click edit, the Builder section disappears,
because it can no longer control the search, however, your previous work is not lost. You
can click Cancel to add the Builder back to the page, and History is still available.
Give the Advanced Search Builder a try with your searches, and if you have comments or
questions, use the link, “Write to the Help Desk.”
