When you perform a search for files or folders, Windows Vista uses the search options (New!) to help customize the search results. You can specify whether you want to search for file names and content or just for file names and whether to include subfolders or find partial matches. For non-indexed searches, you can set options to include system directories or compressed files (ZIP, CAB...). The search options are available in the Folder Options dialog box under the Search tab.
