I have a top-level team site at
http://sharepoint and an enterprise search center site at
http://sharepoint/sites/search. There is an alternative access mapping for the web application - sharepoint.int.company.com.
I'm finding that using the normal search field of the team site results in the site sending the user to
http://sharepoint/sites/search/Pages/results.aspx?k=marketing&cs=This%20Site&u=http%3A%2F%2Fsharepoint. This page doesn't return any results. If I manually change the URL so that 'u=sharepoint', or the 'u' parameter is completely removed, and I refresh the page, then the search page returns results.
How can I update the team site so that is doesn't pass the 'u' parameter across to the search center?
