Quick Search Guide

Search Scope

You can define the scope of your search to get the results most appropriate to your needs. When you type any search term you will see several options.


Search scopes available in OneSearch


  • Everything (default): Search everything the Libraries have access to, using data from both Adelphi Libraries and elsewhere. This includes information about journal articles, book chapters, and other details within works. 
  • Library Catalog: Search the Libraries’ own information about our holdings. This contains the most accurate information compiled by Adelphi librarians, but does not go down to the article or chapter level.
  • Streaming Media: Search videos or audio recordings to which we have access.
  • Course Reserves: Search materials that are available through course reserves.

Expand your scope

If you don’t find what you are looking for, try selecting the “Expand beyond Adelphi Holdings” option in the search results sidebar. From there you can request items through Interlibrary Borrowing.



Tips for Keyword Searching

The following features apply to text fields in both Simple and Advanced search.


Operators (In all caps as shown) allow you to refine your search by combining terms.

AND Search for results with both terms. This is the default operator for multiple search terms and is usually not necessary.
    Example: civil AND war (or just civil war)
OR Search for results with either (or both) terms.
    Example: civil OR war
NOT Exclude the term after the operator.
    Example: civil NOT war


? Match one character
    Example: dr?ve (matches drive, drove)
* Match multiple characters
    Example: cultur* (matches culture, cultural, culturally)


" " Quotation marks group terms to be matched as a phrase.
    Example: “Shakespearean tragedy” (only matches records containing the exact phrase)
( ) Use parentheses to group terms together in conjunction with operators.
    Example: Shakespeare AND (tragedy OR sonnet)
