Atlas Search¶
MongoDB’s Atlas Search feature offers fine-grained text indexing to enable advanced search functionality without any additional management required. Atlas Search provides options for several kinds of text analyzers, score-based results ranking, and a rich query language.
Beta
Atlas Search beta is available on all cluster tiers running MongoDB 4.2. Non-Atlas MongoDB deployments can use text indexing.
Getting Started¶
To get started creating and querying an Atlas Search index, see the Atlas Search Tutorial.
