Auto suggest not working for documents indexed by API

suggest only has terms from documents indexed by crawling. It doesn’t have terms from documents indexed by API api/admin/searchlist/doc. This was working in fess.version=13.10.2 and broken since we upgraded to fess.version=14.4.0
Is there any new config to be updated. Can you please help.

Does it reproduce in the latest version?
