Unable to do Person Search on Competencies, Languages, skills etc in Directory

Content (required):

Hello,

As per Oracle Documentation Person-Record Keyword Searches (oracle.com)

"The application searches for keywords in these attributes: department, person number, job name and code, position name and code, person name, primary email, primary phone, work location, competencies, language skills, licenses and certifications, school education, awards and honors, memberships, interest areas, and areas of expertise".

I am unable to search Employees in Directory based on competencies, language skills, licenses and certifications etc.

Is there any setup needed for this?

For example: From a Manager's login i try to search his Direct Reports who has "French" language in talent profile. But the search does not picks up the employee when searched with French. Is there any setup/process needs to be run?
