I have my application migrated from sitecoreXP 8.1 to sitecore commerce 9 update 1.

Searchbox suggestion is working fine on storefront pages(which are SXA compatible). 

I was able to successfully add the search-box to legacy pages(Eg:- career page).

But, search-box suggestion is not working on any of the legacy pages.

Any help for using SXA searchbox component on non-SXA pages will be appreciated.

Thanks in advance.
