Development of Search Strategies



Formulate the question; Break your question into
multiple concepts
Locate the proper MeSH/thesaurus for each
concept; Use AND to connect different concepts;
Use OR to connect similar concepts
Refine your search
Too Many? Apply limit options (language, subset,
age, publication type, major heading,
subheading)
Too Few? Explode

PubMed Quick Tips
When you get too many results, try these tips.





Use “quotation marks” to search on a phrase
Use [tiab] to find a word/phrase in the title or the
abstract
Use [ti] to find a word/phrase in the title
Use * to find alternative endings (child*=> child,
children, childbearing)
Use “LIMITS” (language, subsets, age, publication
types) from Advanced Search page to narrow
your search
Exercise:
Find systematic reviews on obesity prevention programs
for Hispanic populations

Finding Relevant MeSH Terms
Use Medical Subject Headings to focus your search.
Do a title word search
TIPS:

End of life care[ti] AND pediatric cancer [ti]



Choose “Abstract” format as your
display setting to identify appropriate
MeSH terms.
Terminal care [mh] AND neoplasms[mh]
Exercise:
End-of-life care in pediatric cancer patients

Search Tips:
Narrow Your Search to Be More Focused

Use the MeSH database


Subheadings: nursing, prevention and control,
therapy…
nursing [Subheading] Links Used with diseases for
nursing care and techniques in their management. It
includes the nursing role in diagnostic, therapeutic,
and preventive procedures.
Restrict Search to Major Topic headings only
Exercise:

Systematic reviews on end-of-life care in pediatric cancer
patients (English articles)

Etiology, genetics, prevention and rehabilitation of
cardiovascular diseases among elderly (major topics),
English articles, published in the nursing and core clinical
journals in the past 5 years
