How to Handle Dynamic Paths

The route I guess is like a string from the client with words string separated by slashes and then optionally at the end you have a query string which is the question mark sort of value equals so can you talk a little bit about how the route handler deals with dynamic paths or query strings or anything. The one important part about this filter system is always you first have to tell like warp what to look for in this certain filter  so if you now forget to add the parameter in your request this filter will not be triggeredlike that's the important part and then it says no like I've expected that this static path has been found.
