how I ca create a route with search url using express : using express how I can create a route such as, when the url /search?s=<SEARCH> is invoked, answers with {status:200, message:"ok", data:<SEARCH>} if <SEARCH> is provided, and {status:500, error:true, message:"you have to provide a search"} if it is not. Be sure to set the http status to 500 too.
