+
+ToolJet integrates with Couchbase to leverage its NoSQL database and advanced vector search capabilities. This enables CRUD document operations, SQL++ queries, and Full-Text Search (FTS) within Couchbase databases. Vector store features support semantic search, hybrid queries, and intelligent application development.
