How to remove "Emphasis" ( _ ) in the search bar of service desk?

[Sami]

Hi there,

In the back end I have added an "Emphasis" ( _ ) to the description text of the request type. But in the customer portal whenever I am trying to search a request it comes with "Emphasis" ( _ ) in the search bar. Please find the attachments for better understand.

Is there any solution where "Emphasis" ( _ ) does not show in the search bar of CUSTOMER PORTAL?
