Nesting: Use parentheses to group search terms and control the order of operations when using multiple operators (AND, OR, NOT).
Phrase Searching: Use quotation marks to search for an exact phrase.
Truncation: Use a *symbol (often ) to search for a word and all its variations.
Wildcards: Use a symbol (varies by database) to replace a letter or characters in a word.
Nesting
Example: (climate change OR global warming) AND policy
Use parentheses to control search order. Databases follow order of operations (like math), and the terms inside parentheses are processed first.
Combine AND, OR, and NOT thoughtfully.
AND narrows results (both terms must be present).
OR broadens results (either term is acceptable).
NOT excludes terms (removes unwanted results).
Check the database rules. Some databases require specific formatting for nesting. Always review the help section for guidelines on using AND, OR, and NOT.
Phrase Searching
Example: "civil rights movement"
Some databases automatically search words together as a phrase, while others require all terms to be present but not necessarily together.
Most databases recognize quotation marks (" ") for phrase searching, but some use other methods. Check the database's help section for details.
Be mindful when using phrase searching. For example, searching "river pollution" may miss articles that use polluted rivers instead.
Truncation (Expanding Your Search)
Example: educat* finds educate, education, educator
Truncation helps find different word endings by using a symbol at the end of a root word.
Truncation symbols vary by database. Common ones include: *, !, ?, #. Check the database's help section to confirm which to use.
Wildcard Searching (Handling Spelling Variations)
Example: wom?n finds woman and women
Wildcards replace a letter or characters within a word to account for different spellings.
Wildcard symbols vary by database and may include: *, !, ?, #. Check the database's help section for specifics.
Alway Experiment & Adjust
If results are too broad, add more specific terms.
If results are too narrow, remove restrictions or use OR.
Try different word combinations to get the best results.
