Explanation:
Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a ‘?’ Is added followed immediately by a query parameter.
To add multiple parameters, an ‘&’ is added in between each.
Hence coming back to question, endpoint would return Patients with name as John and (and is very important here) surname as Bell.
