I personally think this method should run with case-insensitive, since that would be more useful. However, the spec. does not seem to suggest so.
I wonder how you implement your search: case sensitive or insensitive? If case sensitive, how do you make sure that when user searches for "roofing", you also return "Roofing" (otherwise it would be user unfriendly)?
I am not sure about your spec but mine says EXACT MATCH for searches(which means you need to do some magic before you display the search results). There is a string method int compareToIgnoreCase(String str) if you wish to use it as an optional feature. Remember the MUST requirements if you dont have it you will be docked.
