Overview
Your Global Search function is not producing correct results in the dropdown suggestions, as when you type a person name it returns a much larger than usual results count or it seems to populate 'People' results for each of the filter options.
The Search landing page does produce accurate results you hit the search button.
Solution
This problem was likely caused by a SharePoint update that affected the display of results in the TypeAhead Search. It has been fixed in Bonzai version 2.2.15.
For more information about this release and how to update your Bonzai version, please refer to the Bonzai 2.2.15 Release Notes.
