A step-by-step tutorial for building a Kotlin Spring Boot application that performs full-text search on MongoDB Atlas using the Kotlin Sync Driver (not Spring Data). Covers setting up a MongoDB Atlas cluster, loading the sample Airbnb dataset, creating a search index with dynamic mappings, and implementing an aggregation pipeline with compound, text (fuzzy), and range operators. The Kotlin code walkthrough includes MongoConfig, AirbnbRepository, AirbnbService, and AirbnbController classes, culminating in a REST endpoint that searches Airbnb listings by description with a minimum review count filter.
