Do not enable folder search! If you enable folder search then you also have
to check each folder to be searched in and during the search you have to
select the folder. Hence the reason why it is disabled by default. Please
read the description in Razuna for this.
Can you upload the screenshot from your site for us to see how ?
By the way , please go to backend administration of your tenant and do the Upgrade Settings and Reset cache and then login to your tenant again to try the new test search assets.
