When searching for a contact, you can filter your contacts by “tag”. A “tag” is a label that is applied to the contact for identification purposes. For example, you can apply a tag called “vip” to your best customers and then filter the contact list to show all customers with the “vip” tag.
To do this, there is a separate dropdown menu. Just select the “tag”  that you would like to sort the list by and the result will be a list of all contacts that have that tag.
This is helpful for viewing and compiling lists of all partners, leads, qualified leads, unresponsive contacts, etc.
By default, only 25 contacts are displayed at a time. If you click on the arrows at the bottom of the page, you will see the next 25 contacts:
