To access the Contact Search section you want to first click on the green Menu bar in the top left. This will show a few different options but you want to focus on the 'Accounts' option as shown below.
It will take you to a separate screen that has 3 different options: Property Search, Contact Search, And Management Company Search. All options will take you to the same screen but it will be searching specifically for whichever option you select.
Alternatively you can click on the 'Magnifying Glass' on the quick access bar at any point in time and click on the search button to access the same area a bit quicker as shown below.
Now in order to edit the columns you can see, click on the 3 dots in the top right of the page and you will see the options shown below. You can check any of these options and this will allow you to see what is entered into that field without having to go into the contact itself.
