There are a list of alphanumeric characters on stage. Each rows of characters are in lines.
I create a input text field for searching to see whether such line of characters exist in the list by pressing a button.
For example, I want to know whether 5gf6r90s200nnm exist in the list, I just type in those characters in input text and press search button, whether or not this line of characters exist in the list, a message is shown.
