Dear Scott,
If you type the code into the box to the left of the search button the list matching should populate below the search window. Click the right code to add it to the chart. I don't thing this has changed. You may not even have to open up the search window where you see the options for starts with, contains and Google.
I am happy to log in and see what is happening if you like. My email is Claire@amazingcharts.com.
