When you use the Search All Files and Folders feature to perform a content search, or you search for a string of text in a file, not all file types are searched for the specified string.
This change was designed to return common document types such as Microsoft Office, MIME, HTML, and plain-text files. The search functionality in earlier versions of Windows searches all files for the specified string and may return a large number of irrelevant files such as program and configuration files.
As a result of this change, the search functionality can find the same set of files if the Content Index service is turned on or off. In previous versions of Windows, the computer exhibited different behavior if you turned on the Content Index service.
The set of files includes all of the common document types that users create including digital media file types such as picture, music, and video file types. For these file types, you can search the text properties. For example, you can search for the artist field in .wma or .mp3 files, or comment strings in .jpg files. This behavior is a new feature that is not found in previous versions of Windows.
