Do I need to ‘select location’ at each level to do a search?

When doing an advanced search choosing a location at each level will automatically populate the level below with options (eg. when selecting a County the District drop-down box below will turn from grey to white so that you can select an option). You only need to select down to the level of the hierarchy you want to search for and not below (e.g if searching for a County role you can leave the District drop down as the default ‘select location’ and still search).
