Answer: Equality searches, Queries with IN predicates

The search optimization service in Snowflake is specifically designed to improve performance for point lookup queries that return a small number of rows. According to Snowflake documentation and the community consensus (with BD receiving 100% agreement and multiple upvotes), the service optimizes equality searches (B) and queries with IN predicates (D). Equality searches use exact match conditions (column = value), while IN predicates are essentially multiple equality conditions combined. Other options are less suitable: range searches (A) are not specifically optimized by this service, substring searches (C) are optimized by the search optimization service but for different use cases (text pattern matching), and queries with aggregation (E) are typically optimized through clustering keys or other mechanisms rather than the search optimization service.
