Remember, research is a process!
Research takes timeDon’t rush through the stepsHave patience with yourself as we discuss new informationOur discussion today will focus on steps you will take to find information in databases

The Search Strategy1. Pick a topic2. Restate your topic as a question3. Identify keywords4. Develop synonyms5. Phrase searching
6. Boolean searching7. Set up search string(s)

1. Pick a TopicTopics that you select for papers and
assignments at Bryant & Stratton MUST be college level
Example: Global Warming
![Page 5: Gretchen Peterson LIBS 100 W10 The Search Strategy.](https://reader036.fdocuments.us/reader036/viewer/2022082422/56649da65503460f94a91f41/html5/thumbnails/5.jpg)
2. Restate Your Topic as a QuestionA good research question for a college class
is not just a definition, but a question that asks for deeper levels of information
A good research question for a college class cannot be answered with a simple yes or no answer
Example of a good research question: What are the causes and effects of global warming?
Example of a bad research question: What is the definition of global warming?

3. Identify Keywords Look at your research question to
identify keywordsKeywords describe major concepts in
your research topicKeywords will help you find
information on your topicYou will use your keywords when you
search for information on your topicKeywords will not be words like: a, an,
the, and, or, but, in, of, for, on, into, from, than, at, to, as, also, probably, however, very, this, that, those, is, be, see, do
See p. 6 in Barker/Terry for more discussion about keywords
![Page 7: Gretchen Peterson LIBS 100 W10 The Search Strategy.](https://reader036.fdocuments.us/reader036/viewer/2022082422/56649da65503460f94a91f41/html5/thumbnails/7.jpg)
3. Identify Keywords Our research question is: What are the
causes and effects of global warming?What do you think the keywords would be?
CausesEffectsGlobal warming

4. Develop SynonymsWhat are synonyms?
A word or words that have the same or almost the same meaning as another word or words
Synonyms are similar!We develop synonyms in order to make sure that
we find as much relevant information as possibleSynonyms should be incorporated into your
searchesExample: What are the causes and effects of
global warming?Synonyms for global warming= climate change,
greenhouse effect

5. Phrase SearchingYou only use phrase searching when one
or more of your keywords is made up of more than one word
Searching for the keyword causes is not considered phrase searching
Searching for the keyword “global warming” is an example of phrase searching
Phrase searching is often times indicated by the use of quotation marks around your phrase
You don’t need to use quotation marks around your keyword if it is made up of just one word
![Page 10: Gretchen Peterson LIBS 100 W10 The Search Strategy.](https://reader036.fdocuments.us/reader036/viewer/2022082422/56649da65503460f94a91f41/html5/thumbnails/10.jpg)
Boolean SearchingWhat is Boolean Searching?
Boolean Searching refers to use the use of Boolean Operators used to combine keyword together
Boolean Operators include: AND, OR, and NOT
AND narrows your search resultsOR expands your search resultsNOT narrows your search results
Most of your searches will be AND searches
What on earth does all of this mean?

Boolean Operator Activity Time!

Venn DiagramsVenn Diagrams date back to the 1880s and are
used to demonstrate set relationships in the fields of probability, logic, statistics, and computer science
You don’t need to understand the math behind Venn DiagramsYou will need to understand some key points about
Venn DiagramsVenn Diagrams are often used to demonstrate
Boolean searchingVenn Diagrams are representations of how the
different Boolean Operators impact search resultsSee p. 26-27 in Barker/Terry for more information

OR Venn Diagram Example: Chocolate OR Pickles
Chocolate Pickles

AND Venn Diagram Example: Chocolate AND Pickles
Chocolate Pickles

NOT Venn Diagram Example:Chocolate NOT Pickles
Chocolate Pickles

7. Set up Search StringsSearch strings are NOT the same as your
research questionSearch strings incorporate your keywords,
synonyms and Boolean OperatorsAs a result, search strings look a little
strange!Here is an example of a search string, using
our global warming research question:(“global warming” OR “climate change)
AND causes AND effectsYou may have to create several search
strings in order to get to the information that you really need
