An easy way to help users search for information in SharePoint is to create query suggestions. Query suggestions are words that appear under the search box as users type a query.
SharePoint automatically creates a query suggestion when users have clicked a search result for a query at least six times. For example, if users have entered the query word “coffee” and then clicked on a search result six times, then “coffee” automatically becomes a query suggestion.

Automatically created query suggestions will not be overwritten when you import new ones. However, if you want to import additional query suggestions, you should export the existing query suggestions file, update it, and then re-import it.
