Boolean retrieval is a foundational information retrieval model that retrieves documents based on exact matches to queries formulated with Boolean operators (AND, OR, NOT). It treats documents as sets of terms and queries as logical expressions, yielding a binary result: a document either perfectly matches or does not.
Boolean retrieval is a fundamental method for finding documents that exactly match a query built with logical terms like AND, OR, and NOT. It's very precise but doesn't rank results by how relevant they are. Modern systems are evolving to handle much more complex logical queries efficiently, addressing the performance and memory issues of traditional approaches.
