EPCM.getSAPTop().LSAPI.getSearchProviderPlugin not working

Hello,

Portal version: 7.3

I have a scenario where I have used EPCM.getSAPTop().LSAPI.getSearchProviderPlugin to search on Portal content.

I see that it works on DEV Portal, i.e., if I type something in search input box and it first shows list of results matching my search input field and when clicked on one of the suggestion, it navigates to that page.

But same functionality, when tested on TEST portal, gives "No suggestions".

Any idea what might be missing here?

Thanks & Regards,

Amey Mogare
