Riders of the Red Fork says that while it is "in your deck, it meet the criteria to be found by any search effect".
Can I use Family, Duty, Honor to search for it even if it is not within the top 5 cards of my deck?
What about opponents' search effects? Can they (for whatever strange reason) search for your copy of RotRF (I assume here that if they can, it would still go into your hand, not theirs)?
Family, Duty, Honor card text:
When revealed, search the top 5 cards of your deck for any number of House Tully cards, reveal them, and add them to your hand. Then, shuffle the other searched cards back into your deck.
