Advanced Database Searching

Below, you will find a number of strategies one can use to help make searching more streamlined. While they are not imperative to doing academic research, these techniques will help you find a larger number of sources that relate specifically to your research topic or query. In turn, making the research process quicker and easier.

Please feel free to adopt the following techniques into your own searching habits. If you are ever struggling to navigate a database or have questions about searching strategies, please reach out to your librarian for assistance!

Database Search Operators

These are words, phrases, and symbols you can embed into your search string to refine your search.

Name Operator Span Result

Boolean

Operators

 

AND Narrow Records containing all the words it separates
OR Broaden Records containing any of the words it separates
NOT Narrow Records that do not contain the word following it
Phrase " " or ( ) Narrow Records containing the exact phrase within the quotes or parenthesis
Wildcard ? Broaden Records containing variable spellings of a word
Truncation * Broaden Records containing variable endings of a root word

Limiters

"Limiters" or "filters" are ways you can further refine your search results. These are options that you will typically find either in the drop-down menu of a database's "advance search" option or on a left or right-hand side navigation menu. The amount and type of limiter options available will vary between databases. When you get into ultra-specific subject areas, a database might even offer unique limiters you cannot find elsewhere.

Limiter Purpose
Select Field Choose which area or field to search
Controlled Vocabulary Utilize database's subject headings
Peer Reviewed Limit to articles examined by a panel of experts
Full Text Limit to items which are available immediately 
Publish Date Limit to a specific date range
Source Type Limit to a specific type of resource (book, article, DVD, etc.)

Example Searches

Hairless Cats

Prompt: I adopted a hairless cat, but my roommate is still allergic! What besides dander could be causing their allergies?

Search terms: (cat OR feline OR "felis catus") AND allerg* NOT dander

Search Element

Result
cat OR feline OR "felis catus" This will bring in any article that mentions one or all of these terms. If you just searched "cat", you would cut out any articles that use the term "feline" instead
AND allerg* This will bring in articles that mention cats AND allergies. By truncating allergy to allerg*, you will also bring in any articles that include allergy, allergies, allergen, and allergic
NOT dander This will remove any articles that talk about dander so you can learn about alternate causes

Results
dolphin OR delphinus delphis This will bring in any article that mentions one or all of these terms. This will return articles that refer to dolphins by either their common or scientific name
