Couchbase Server 5.5 and 6.0 introduce significant enhancements to the Full-Text Search (FTS) service, offering improved performance and manageability with a new indexing engine, Scorch, which reduces indexing time by 50% and decreases data size on disk by up to 70%. These releases also finalize the geospatial search feature, making it production-ready, and expand language support by adding 11 new language analyzers to the FTS, broadening Couchbase's global market reach. The updates are designed to better meet enterprise use cases, and users can explore the new features through the index creation UI or JSON-adjusted index definitions, with further guidance and examples provided in the updated documentation and training resources.
