Some changes based on comments from Aaron Leventhal. Very good suggestion by Aaron Leventhal. I assume that it was thoroughly discussed. Not sure what this comment means. See my earlier comment about 4.15.
Differences are really hard to spot.
But I don't know if it is worth trying to clarify. For checkpoint 9.8, the idea of the 'alert' seems like only half the requirement. Alert the user when there is no match. If the search wraps back to the beginning of content, alert the user prior to wrapping. A wrapping search is one that restarts automatically at the beginning of content once the end of content has been reached.
