If the search object isn't huge in size, then go with using a ViewState. A ViewState is perfect if you only want the object to live for the current page's lifecycle.
First of all Viewstate is per page where as the session exists throughout the application during the current session, if you want your searchobject to persist accross pages then session is the right way to go.
