Search library, ash heap or hand

If i play a creation rites, and i search my library for a discipline card and don't find any, can i then go through my ash heap and take one from there?
The reason i am asking is that card text is "or", not "and".

Creation Rites,
Action,
1 blood
Non-sterile, Archbishop, Priscus, Cardinal or Regent,
+1 stealth action. Requires a ready non-sterile archbishop, priscus, cardinal or regent. Put this card in play; it becomes a 1-capacity vampire. You may go through your library (shuffle afterward), ash heap or hand to find a Discipline card for this card. You may move a blood from the acting vampire to this vampire. This vampire is not considered unique, cannot act this turn, and is the same clan as the acting vampire.

LSJ was in the process of moving all of these cards from "or" to "and", although that had its own challenge. You can look everywhere, though.

Right.

The "or" text invited others to question whether one could look in the library
and, finding none, then be allowed to complete the search through the ash heap.

So "and" is used to avoid that nit. At the expense of this one, apparently.
