As of early January 2019, the radius search functionality in a Tax Search is not working properly. When you click the drop down arrow to select the radius distance you want to use, the selected value never actually appears in the radius field:
The workaround at the moment is to click on the Map tab in the upper right and enter the center point of your search area in the Jump to Address field (hit the enter key on your keyboard when you are finished typing the address):
That will center the map based on the address you entered. Now, click on the radius icon at the top of the map (it is between the clock and the rectangle) to enable the radius drawing tool:
When you click the radius icon, it turns yellow, indicating that it is enabled. Now, place your mouse cursor so it is right at the point of the red pin that represents your center point address. Click and hold down the left mouse button and drag away from the red pin. As you drag, a blue shaded circle will start to appear and the radius distance will start to increase:When you have achieved the desired radius distance, let go of the mouse button and it should lock the shaded search area into place, using the radius you determined. Remember, radius will be the distance between the center point and the edge of your search area circle. The distance across your search area will actually be twice as large. So, if you choose a radius of a mile, the width of the circle that represents your search area will actually be two miles.
Once you have your search area defined, you can either go back to the Criteria tab to enter additional criteria (if you want to increase/decrease the number of matching tax records) or click the Results tab to view the tax records for the properties that meet your search criteria and fall within your shaded map area.
