Dave,
Adding "Mac OS X - Using Disk Utility to Repair a Disk" will result in those words being included in searches for any of those (individual or groups of) words.
Unless a site's robots.txt file excludes a particular page from being spidered by search bots, every word on every page of a site will be indexed, and provide matches when any text on them is searched for.
Thank you. Very clear and helpful.
