For example, when I key the word "Libram" the search function displays a long list of Librams and refuses to search anything else.
What I want to know is: What is a Libram? Why would I want to use one? How are they used? Can their effects be removed or reversed?
But the lousy search function won't allow me access to potential answers for those questions and Blizzard is clearly unprepared to answer them, insofar as they have removed the original documentation for the game from their online websites and have failed to replace it.
So, tell me then why I should continue playing WoW?
