Search Button not working in Solman 7.1

Hi,

We are using Solman 7.1. However, in Solar02,  when I search for anything from the left tree structure using the search button ( The binocular button ) , it says text not found. We generally get a list of folders in that left tree. Any text that is present in that tree structure, if I search by that, it does not return anything.

Is there any Snote that is available for this issue.
