GET form submission parameter not passed

[teckays]

I have the following use case

<app-route path="/search/"></app-route>

<form action="/search/?q={{q}}" method="get">
    <paper-input-decorator>
        <input is="core-input" value="{{q}}">
    </paper-input-decorator>
</form>

when I type in a query and submit the form, the urls is: /search/?

if:

<form action="/search/{{q}}" method="get">
...

If I type in "foo", url is: search/foo?

How to make the form action to look /search/q=foo?

[erikringsmuth]

Maybe this?

<form action="/search/q={{q}}" method="get">

This might be more of a Polymer template syntax question...
