Ok.. I search for Shadowknight Epic Weapon, and I get
Shadowknight (EQ2 Subclass)
Epic Weapon Quests (EQ2)
Category:EQ2 Epic Weapon Quests
Beastlord Epic Weapon (EQ2 Quest Series)
Guardian Epic Weapon (EQ2 Quest Series)
Berserker Epic Weapon (EQ2 Quest Series)...
...and on down the line, many classes listed except Shadowknight, the one I searched for.
Mystic is also missing from the list. If I go to the Epic Weapon Quests page, they are all listed. Going to each page shows that their links and page titles are formatted to match the others, no spelling errors, etc. Searching direct for Mystic Epic Weapon gives similar results.
The pages are there, and seem to be formatted correctly. Can someone with more Wiki XP than me figure out why the Search can't find them directly???
