Faceted Search (Wikipedia)
Wikipedia’s article on faceted search — augmenting keyword search with a faceted navigation system that lets a customer narrow results along multiple independent dimensions at once.

Key points
- A faceted classification system classifies each item along multiple explicit dimensions (facets) corresponding to its properties, letting the same content be accessed and ordered multiple ways rather than committed to one predetermined taxonomic order.
- Facets are derived either by analyzing item text (entity extraction) or from existing structured fields (author, format, language, and similar attributes already present in the underlying data).
- By 2014, roughly 40% of the fifty largest US-based online retailers had implemented faceted search — an early sign of how quickly the pattern became a baseline expectation for retail search, not a current-day figure.
- Faceted interfaces are also common in library online catalogs (OPACs), letting patrons narrow by attributes like format, date, and subject alongside a keyword search.
