Description

Paginator builds its links from two different sources:

• url($page), which backs the page-number links and the Jump dropdown, reads request()->query(), the real query string.
• previousPageUrl() and nextPageUrl() read request()->except('page'), which is the request's whole input bag.

Real query-string filters such as ?search=foo are still carried into the links. Only server-side merged input is excluded.
