DirectIQ allows you to filter contact lists by list name, list quality, and last modified date. First, open Contacts -> My Lists. Click the button with the filter icon located at the end of the line with the field names to see the filter line.
Select values to filter from the drop-down list for quality and last modified date and enter a value in the text box to filter by name. The contact lists are automatically updated after selecting a value from the drop-down list or after entering at least three characters into a text field.
If you click on the cross, that appears instead of the filter button, then all filters will be reset and the filter line will close.
