Determine the type of query for "SearchAction"

I am struggling to find a solution. I am looking for a way to define a search keyword. For the website, you can find vehicle information by wine number. The same thinking process as finding a phone number

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "WebSite",
  "url": "https://www.example.com/",
  "potentialAction": {
    "@type": "SearchAction",
    "target": "https://query.example.com/search?q={search_term_string}",
    "query-input": "required name=search_term_string"
  }
}
</script>

      

        
        
        
      

    

I'm trying to let google ( Link Search ) know that "search_term_string" is a wine number. It would even just take exactly 17 characters.

Any ideas? Does this scheme support her support? Does it support phone numbers?
