Start Your Search

Choose Your Keywords

Once you've ensured you understand your assignment and know your research topic, it's time to select your keywords. Some words from your topic may not be relevant to the search, as shown in the example below. Use only the most important elements as keywords.

Example: ~~Does~~ exercise ~~reduce BMI~~ in overweight youth?

Synonyms for Example Keyword Search
exercise	overweight	youth
"physical activity"	obese	pediatric
movement	obesity	child
		adolescent

Add Connectors

Since library databases work differently from Google, you may find that entering a sentence or question into the Search Everything box on the library homepage doesn’t yield relevant results. Connectors like AND, OR, and NOT, often called Boolean operators, help the database search for your keywords in a specific way.

Tip! Capitalize connectors so the databases see them as connectors and not keywords to search.

Connectors AND, OR, NOT
AND (-)	NOT (-)	OR (+)
Shrinks your search results	Shrinks your search results	Expands your search results
Only shows results that contain both keywords	Will exclude any results that have a second keyword	Allows for either keyword or an intersection of both
Example: I want both overweight and youth in my search results.	Example: I only want overweight, I do not want youth in my search results.	Example: I'm fine with either overweight or youth, or even both in my search results.

Use Advanced Search Strategies

There are a few things you can do to help make your searches more precise and possibly retrieve more relevant results.

Use quotation marks around a set of keywords to search those exact words as a phrase.
- Example: "physical activity"
Use the asterisk (*) at the end of a root word to search all the endings of a word.
- Example: obes* will search for obese, obesity, etc.
Use parentheses to group related terms together.
- Example: (exercise OR "physical activity" OR movement)

Build a Search Statement

Here is how you put it all together in a search statement: (exercise OR "physical activity" OR movement) AND (obes* OR overweight) AND (youth OR pediatric OR child OR adolescent)
