Here I have an html file with just a form element and a single text input element in it, and a submit button. I am setting the action attribute of the form element to the search path and the method to get. This way when the submit button is clicked the user will be directed to the search path with the query string set to the values given in the text input field.
So then when this example is up and ruining it is serving up the single html file at the root path, and the search path which at this time is just displaying the query in the browser window. Nothing major at this point but the basic idea is all ready there and working it is now just a matter of what I do with that query in the back end system.
