Couchbase Server 4.5 introduces a preview of Full Text Search (FTS) as a feature integrated into its ecosystem, following its initial release as a standalone Developer Preview. FTS enables case-insensitive searches, supports typo tolerance, and uses advanced text analysis with various prebuilt analyzers for multiple languages. It provides multiple query types and scoring mechanisms, backed by the Bleve open-source project. While Couchbase FTS offers a seamless integration for full-text indexing of JSON documents stored in Couchbase, it remains in developer preview and is not yet suitable for production use, unlike established tools like ElasticSearch or SOLR, for which Couchbase maintains connectors. The feature allows users to run faceted searches and create aliases for indexes to facilitate app development without altering index names. Although FTS is not yet production-ready, Couchbase is working on improving its performance and multi-node support, with plans for future integration with N1QL and continued support for existing connectors.
