You need the following syntax in your search.xml file:

<Url type="application/x-suggestions+json" template="http://www.example.com/searchcontroller/{searchTerms}"/>

If someone starts typing in fre the method on the search controller that looks for suggestions should then return a JSON array of suggestions in this format:

["fre", ["frequent", "freeze", "freak"]]

Have a look at Mozilla's documentation
