I've been making a custom SharePoint Web Page and I had a basic search bar that searches either Google or our SharePoint site depending on which of two radio buttons are selected upon searching. If the SharePoint button is selected, I would like to have search suggestions pop up based on user input. Is this possible to automate in SharePoint? Most guides I've seen online are performed by populating a list and then pulling suggestions from that list, but this is not what I am looking for. I'm looking for actual suggestions from the site collection.
