I wouldn't say that they are completely useless, but they havebecome more complex and hard to use with the bloating ofinformation on the internet. It is much harder to find relevantcontent. Different search engines try to find what you need indifferent ways, but because they are more specialized the way youare searching affects your results and asking differently is theonly way to get what you want.Other times, the information that you want just isn't on theinternet, at least in the form we are looking for, and so we thinkthat a search failed when it is actually that no one has compiledthe information we are looking for.
