how do I run a search in custom fields for contact type?
It sounds like you have created a custom field called ‘Contact Type.’ If this is the case, when you go to a contact search, and head to the Custom Field tab of the criteria, you should see a criteria piece for this field.
Depending on what type of field it is, the search function may differ. If it is a standard text area field, you should see Contact Type in the Custom Field search criteria, with a dropdown next to it that defaults to ‘Starts with’ and has a field for you to type in criteria.
Once this is done, you can run your search, to display your results!
