Summary:

When we Search using following navigation, it doesn't return anything unless we search a full question / text, Which is not making any sense at all - Please refer to the screenshot which confirms this behavior !

Me-> Personal Brand -> Ask and Expert -> Search for Existing Questions.

Is there any configuration or setting which can be used to enhance this behavior.

Cannot find anything in the implementation guides or Oracle support existing documentation.
