Answer: It improves the performance of equality searches.
The Snowflake Search Optimization Service is specifically designed to improve the performance of queries that use equality predicates (e.g., WHERE column = value). This is clearly stated in Snowflake's documentation and supported by the community discussion where multiple users reference 'equality searches' as the key benefit. While one comment suggested both A and D, the official Snowflake documentation and the majority consensus (including the highest upvoted comments) point to D as the correct answer. Option A (range searches) is not the primary focus of the search optimization service, option B describes a different concept (multiple clustering keys), and option C is incorrect because the service doesn't improve performance for 'all queries' - it specifically targets queries with equality predicates.
