You ask the librarian for exactly: "Books over 500 pages, published before 2026."

The system uses strict, rigid logic. If a book has 499 pages, it is ignored entirely. It is perfect for exact numbers, dates, and strict business rules.

You ask the librarian: "Do you have anything about growing a marketing agency?"

The system understands intent and related concepts. It finds books on "advertising," "B2B growth," and "client acquisition" because they share the same conceptual neighborhood.
