On the Pages and Offer pages you can narrow down the entries you see by using the Search bar.
You can add the attribute you want to search for (eg: Name, offer type, etc) and enter the value you want to filter the entries by. You can add multiple attributes.
To refine the results you see on the page, navigate to the cog on the top right of the table. From there you can select which columns to view on the page.
Note: Amending the columns in the view is only available in the Offer page
