title: Rails Search Form
body: <p>I'm creating an application that tracks users and achievements (think, xbox live, etc.) These tables are linked via a join table.  I would like to have a search form on my index that lets users type in a users name and a new page is loaded with a list of all achievements that user has earned.  I'm not entirely sure how to set up this search form, on the index, to actually search the user table and return the results on a new page.  Any help would be greatly appreciated.  If you require more information then I'll be happy to provide it.</p>
