All pages in the Realtime Register domain manager displaying listings have a Filter button available. Click on the button Filters, and a form overlay will pop-up. The entry fields containing information are used in the query.
Each entry field has an operator for the value entered. You can click on the drop down list button to select another operator than the default =. Click on the Filter results button to start your query. The button Clear filters removes all entered values. The Filter form overlay will stay visible, even if it loses focus.
