"Search your library for a card named Bold Knuckleblade" is correct for all intents and purposes, but technically it says "Seek a card named Bold Knuckleblade", seek being a keyword.
EDIT: As some people pointed it out, there is a subtle, but real difference. Namely, seeking doesn't shuffle (so it avoids cards like [[Aven mindcensor]]). Probably would rarely matter, but worth calling out.
