For 'People', how to filter the search for Profile Types? Ex; Registered, Seller, Advertiser, Blogger, etc...
For Pages, filter it by created categories. Ex; General, Music, Education; etc...
For Groups, filter it by created categories. Ex; General, Business, Organization; etc...
For Events, filter it by created categories. Ex; General, Business, Automobile; etc...
There are no search criteria for profile types because those criteria are based on custom fields. If you would like to allow such filters, perhaps you can create a custom field which stores a different value in different profile types/categories.
