SoCar, South Korea's No.1 car-sharing business, is revolutionizing user-friendly search services with MongoDB Atlas Search. The company has expanded from vehicle sharing to comprehensive mobility platforms that include lodging and parking reservations. To provide a seamless booking experience, SoCar integrated data from various external accommodation booking channels into its own inventory. This required a flexible database system like MongoDB Atlas Search, which supports diverse data formats and structures. The platform also benefits from advanced query capabilities provided by MongoDB Atlas Search, enabling complex queries with multiple conditions and operations. Furthermore, the integration of geoWithin operator is underway to support map-based search functionalities. SoCar's adoption of MongoDB Atlas Search has significantly improved search performance and user experience, making it a suitable choice for developers looking to integrate robust and flexible search capabilities into their applications.
