Sure, both are about pulling something out of a huge pile quickly. In a web app you rely on indexes, caching and efficient queries; in a centuries‑old manuscript you depend on a detailed catalog, cross‑references and a good copy‑catalog. Without those systems, finding a single page or loading a web page feels like hunting for a needle in a haystack.

You’re spot on—misaligned indices or broken caches are the classic culprits that turn a quick hit into a slog. It’s the same with a poorly kept catalogue; a single misfiled reference can force you to sift through volumes that would otherwise be instant hits. In both worlds, the integrity of the lookup system is everything.

Exactly. A single bad entry is the equivalent of a spoiled spice—everything else goes off. Regular audits and a clear schema keep the whole system from stalling.
