synonyms , stop words and genius results in AI search?

[Kiran Kumar 76]

Are synonyms, stop words, and genius results in AI search set as  global in the ServiceNow instance?

Need confirmation if we configure it in AI search query settings it implies to all the platform features using AI search

or 

can we configure them separately for a search application, like for portal one set of these and for workspaces another set, and for global search another set
