Now, extract from your topic the words and phrases
representing each concept. In separate columns or lines, list
synonyms or alternate ways of expressing each concept. We
will enter each idea in a separate search box. Stringing different
aspects of the topic together would limit the power and flexibility
of your database search.
ADHD OR attention deficit hyperactivity
disorder
AND
curriculum
Note the use of "OR" to retrieve all
articles containing either term (the union of A+B). Use "OR"
when either word can represent your idea. The Boolean "OR"
broadens your search, increasing the number of hits (results).
Connecting separate concepts with "AND"
narrows the search by ensuring that both ideas are mentioned
in each article you retrieve (intersection of A and B).
Enclosing words in quotations retrieves the
exact phrase: "sequential learning."
