Use % wildcard(s) for partial matches. EXAMPLE: Enter 'Volunteer%' as your Activity Type to match any activity whose type is 'Volunteer' + any other words (e.g. Volunteer for Open House).
If multiple boxes are checked for Contact Types, Groups, Tags and Location Types, the selections are combined as OR criteria (e.g. checking 'Group A' and 'Group B' will find contacts who are either in 'Group A' OR 'Group B'). All other search fields are combined as AND criteria (e.g. selecting Tag is 'Major Donor' AND Country is 'Mexico' returns only those contacts who meet both criteria).
