How do you add multiple liquid variables to a link in Looker?

I’ve followed this link https://docs.looker.com/reference/field-params/link on how to add a link to a dimension. 

So I was following this formula: 
 

dimension: artist_name {

link: {

label: "Google"

url: "http://www.google.com/search?q={{ value }}"

icon_url: "http://google.com/favicon.ico"

}

}

BUT, I need two different values in that URL link. For example, I need to add Lead ID and Client ID to that URL. And it only seems to work when you add one value.
