Please see below brief details.

We are implementing "Related Search", In this implementation we want to display links that users had searched and visited (in the some articles mentioned if user clicked a link 6 time then this link will added into suggestion). We are using the /_api/search/suggest?querytext='sharepoint' api call. Right now it returns only current users visited/clicked links. We want to display links which are visited/clicked (6-times) by all users. Any idea regarding this?
