I cannot find certain information when searching. Can I add this?

This is certainly possible! To do this, go to the relevant search page in the backend of your environment. Here, go to Manage views. You can add a new view here.

If you then click on No columns found under the Columns option next to the new view, you can add all the columns you want to see!

If you want to adjust the columns of an existing view, this is also possible by adding columns to the Selected columns under the Columns option for that view. Then click the Go to view button.
