Admins in Responsive can set up Related Word Sets in the Organization Settings to boost the keyword search. Content Library related words pull in related words during a Content Library search. The related word sets act as a dictionary of similar words, synonyms or antonyms, as grouped by the user. By default, the system has a set of related words in UK-US English that users can leverage.
When words have different spellings in US English and UK English but you want to fetch them together (Utilise [UK] and Utilize [US] for example); or when abbreviations are used in content but you want to fetch both words while searching (End of Day and EOD for example). For instance, if you are in the Healthcare industry you may have multiple ways to reference or abbreviate HIPPA / Health Insurance Portability and Accountability Act.
For a visual guide, refer to the Academy course on Content Library Related Words.
You must have access to Organization Settings to create related words.
