Development of Search Strategies







Sep 2007
Formulate the question
Break the question down to various concepts
Find the right MeSH/thesaurus for each concept
Combine various concepts using Boolean operators
(AND, OR, NOT)
Apply limit options (language, subset, age,
publication type, major heading, subheading)
Run the search
Modify search strategies and rerun the search
7
Why Use Index Terms (MeSH)?



MeSH headings are an efficient way to find
information on “concepts” or topics where
authors use different language to discuss the
same ideas.
Using MeSH improves precision and accuracy of
subject searching.
Searching for words in the keyword indexes may
not retrieve relevant articles.
Example: physical therapy
“Storytelling as therapy: implications for medicine.”
Abstract: Storytelling is an art developed during the
beginning of human history, probably to teach the wisdom of
generations past, including basic mental and physical health
principles…

Locating MeSH - 1

Sep 2007
Do a Title word search.
e.g.
- Treat* [ti] AND repetitive stress injur* [ti]
- Change display format to “Citation” to see
assigned MeSH for the concept.
9
Locating MeSH - 2

Sep 2007
Search the MeSH database
 Scope Note
 Subheadings
 Major Topics
 Explode
10
Boolean Operators


Sep 2007
OR (use to join synonyms)
 Vitamin C OR Ascorbic Acid
 doctors OR physicians
 tumor OR tumour
 injuries OR accidents
AND (use to combine concepts)
 Vitamin C AND cancer
 doctors AND managed care
 color AND vision
 injuries AND automobiles

Tips on PubMed Searching




Search field tags are available [ti]
Forced phrase searching in quotes “”
Explode is automatic
Use truncation (*) to broaden your search
(e.g. child* => child, children, childbearing)



Sep 2007
Boolean operators processed left to right
To find in-process citations: Use keyword search
and limit your search to last one year.
Keyword search: looking for terms in the title,
MeSH and an abstract.

Sep 2007
Save search strategies
Provide automatic email updates
Set up filters for specific research
papers, e.g. systematic reviews, metaanalysis

Setting up filters for RCT and meta analysis




Sep 2007
Select ‘Filters’ in the far left menu, and then select
PubMed.
Select ‘Search’ and look up ‘randomized controlled
trial’. Select Randomized Controlled Trial under the
matching filters list and then check the ‘Add’ box
to automatically add RCT as one of your filters.
Go back to ‘Search’ and repeat this with ‘meta
analysis’.
