Are you finding too much or not enough information? Try using boolean operators and truncation symbols, or use an alternative, narrower, or broader keywords to vary your results.

To retrieve the most relevant search results, you will need to construct a search string.

A search string is a combination of keywords, truncation symbols, and boolean operators you enter into the search box of a library database or search engine.

Example: educat* AND student* gives results that include "education, educator, educating" and "student, students".

Use the information on this page to help you construct effective search strings.

Truncation or wildcard symbols allow you to look for variations of words. They often broaden your search results.

For example, searching on sport* would bring up variations such as sport, sports, sporting, sporty, etc.

Note: The truncation symbol varies by database. Consult the database’s “help” or “search tips” pages for details.

Databases are different from Google.

Databases are pickier about spelling.

Databases don't automatically truncate.

Use a database's Advanced Search option to enter search strings with Boolean operators and truncations.

Avoid natural language; use keywords, subject headings or prompts.

Next, go to Advanced Search and use "OR" to string together these synonymous terms (box 1): education OR schooling OR learning

Use "AND" to connect the first concept with another concept (box 2).

If you need material on both sides of the topic, add "controversy OR debate" (box 3).
