Empty search / null search
A term that covers two situations: when the user hasn't typed anything yet (empty query), and when what they've typed doesn't match any product (zero-results query).

Empty query: the user opens the search bar without typing anything; the store can display featured products, trending items, or best sellers. Zero-results query: the user types something that generates no results; common causes are vocabulary that differs from the catalog, unresolved typos, or a product that doesn't exist. The distinction matters for analytics and strategy: the empty query suggests an opportunity for inspiration, while the zero-results query signals a gap.

Managing both situations retains users who would otherwise leave. An empty query turned into a suggestions screen transforms indecision into inspiration. A zero-results query with relevant alternatives keeps the user engaged in the purchase process.
