The Tickets tab allows you to filter data based on various parameters. Inside the Tickets module, you can see the right sidebar filled with options to filter your tickets. You can filter tickets based on the type (incident or service request), agents, groups, status, priority, etc.

If you wish to create a custom ticket view for present/future use, you can click add all the filters required and click on the new tick mark present right on the top bar (refer to the screenshot below), and click on save. 

The saved search parameters will be created as a new view, which you can later access from the same tab by clicking on the three-lined icon on the top left corner of the screen. ( Ticket list )
