The task:

To create a very user friendly search and output tool that:

- When you type in a document reference number (*box contents*) into a search box, which, upon pressing the command button, shows a
*box reference number*, thus indicating whereupon that particular document is situated.

- Is so easy a child could use it to find where things are situated.
