Advanced Find
This feature enables you to search for data with very precisely defined search criteria. You can link many conditions to search the data to the desired level of detail and get the information you want.
This feature is also great for preparing data for export to Microsoft Excel and then analyzing it or presenting it in various perspectives using pivot tables.
You can access Advanced Find by clicking on the small funnel on the right side of the Dynamics 365 header
Microsoft provides more information on usage in the Dynamics 365 documentation: Create, edit, or save an Advanced Find search
