You are designing a large-scale e-commerce platform that requires fast and accurate search functionality. What indexing and search strategies would you employ to ensure that users can find products efficiently and accurately?

To ensure fast and accurate search functionality in a large-scale e-commerce platform, employing Inverted Indexes and Distributed Search Engines is a common strategy. These technologies allow for efficient and scalable search operations, as they pre-process and index the data in a way that speeds up retrieval. Full-Text Search Indexing is useful for searching within product descriptions. In-memory caching can further enhance query performance by storing frequently accessed data in memory. However, it's not a substitute for proper indexing and search strategies.
