What is it?
A switch allowing you to control how a search will be done. The options are:

1. The search will take out any name that does not match the entered selection, resulting in a shorter list.
2. The search will position the cursor on the match closest to the entered text. You can use the Up and Down buttons to further search.

What happens if clicked?
The search switches between:

1. Acting as a Filter to Filter out any user that does not match the entered name.
2. Acting as a search tool where the cursor will be located on the name closest to the entered name.
