HNFE 2014 Research Resources: Design a Keyword Search
Your HNFE 2014 assignment asks you to find, read, and summarize information, or evidence, from peer reviewed research articles. An easy way to find peer reviewed research articles is to use a research literature database. To get the best results when searching in a database, develop and use a Keyword search strategy
Step 1: Draft a Research Question
Step 2: Develop a Keyword search to use in research databases:
Choose keywords based on concepts in your research question
Add AND between your keywords to form a search statement to type or copy/paste into databases (see example below)
Step 3: Revise your Keyword Search as needed
Creating a Search
How do you develop keywords from a research topic? Watch this short video to find out!

Searching Tips
Rather than typing a full sentence or question into a search box, using Boolean operators can help you create an efficient and effective database search. Try the Search Strategy Builder, which will create searches out of keywords that you supply!
In order to use Boolean operators, you need to know:
Boolean operators
-
AND: both terms that you connect with AND msut be somehwere in the bibliographic record for that record to be retrieved. AND narrows a search and retrieves fewer articles
-
OR: only one of the search terms combined with OR is required for the bibliographic record t5o be retrieved. OR broadens a search and retrieves more articles
-
NOT: excludes a particular subset, category, or term. NOT requires the presence of one search term and the exclusion of another.
Other special symbols:
Truncation: A symbol, specific to the search interface, which allows the retrieval of all endings for the specified base word. An asterisk (*) isoften used. For example, child* would retrieve records with children, childish, and every other word that begins with the root word "child."
Wildcard: A symbol, specific to the search interface, which allows the retrieval of various spellings of a word. A questio mark is often used. For example, wom?n would retrieve records with women or woman.
Quotation marks: To search for an exact phrase with the words together, in the order you wish to find them, add " " quotation marks around the phrase, such as "physical activity" versus finding an article about physical education and an activity for elementary school students.
Example Boolean search statements using symbols:
(Calcium AND milk) NOT goat
child* AND anxiety AND (exercise OR "physical activity")
alcohol AND medication AND (elderly OR aged OR older adults)
alcohol AND "drug interactions" AND (elderly OR aged OR older adults)
alcohol AND ("medication interactions" OR "drug interactions") AND (elderly OR aged OR older adults)
alcohol AND (medication interactions OR "drug interactions") AND (elderly OR aged OR older adults)
clostridium difficile AND malnutrition AND (elderly OR aged OR older adults)
clostridium difficile AND (nutrition OR diet OR malnutrition) AND (elderly OR aged OR older adults)
