How can I ensure that EDS searches that include unintended Boolean operators will return the appropriate results?

EBSCOadmin includes a setting that allows administrators to set EBSCO Discovery Service (EDS) profiles to handle the words and, or, not as Boolean Operators only when they are entered as all capital letters (AND, OR, NOT.)

An administrator may choose to modify this setting to ensure that users searching for titles or phrases not enclosed in quotations and have these words included do not return poor or zero results.

For example:

  • In the phrase "to be or not to be," or and not would be treated as Boolean Operators and impact the search results. When this EBSCOadmin setting is enabled, or and not are treated as part of the phrase and not as Booleans because they were not entered in capital letters.

  • If a user searches for the book title "Death be not Proud," not is treated as a Boolean Operator causing the book to be excluded from the result list. When this EBSCOadmin setting is enabled, not is treated as part of the phrase and the title is included in the result list.

To modify this setting in EBSCOadmin:

  1. Log in to EBSCOadmin at

  2. Choose the desired EDS profile from the Choose Profile drop-down menu.

  3. On the Searching sub-tab, set Require uppercase Boolean operators (AND, OR, NOT) to Yes.

  4. Click Submit to save your changes.
