I do not know how to do this in the Visual Studio 2008 user interface (I even checked 2010 - nothing). However, there is a way to make changes to this using the registry. The link below should help. It is based on Visual Studio 2005, and it also works for Visual Studio 2008. Just change the registry location.
From: HKEY_CURRENT_USER \ Software \ Microsoft \ VisualStudio \ 8.0 \ Find
To: HKEY_CURRENT_USER \ Software \ Microsoft \ VisualStudio \ 9.0 \ Find
