I do not see any way to use Windows 7 search to search file content ONLY w/o it also including file names. For example, how do you search for files that contain "L:\" and only files that CONTAIN "L:\"? I do not want a list of files that have that in their name (filespec) but only a list of files that have that in their content.
Someone suggested L:\ System.FileName:NOT ~L:\ but that excludes all files with L:\ in their name (filespec) including the ones that contain "L:\".
