This field allows you to choose between searching by name and title, or by all fields, where you can also search in subjects, movements, dates or any other field.
You can combine one or several hierarchies for the search. Use the arrows to display the specific elements belonging to that hierarchy. If you click on a parent element, you should know that all the elements it contains will automatically be selected. If you want to select something specific, check only the given box. Your search will be reflected in the top green box.
