What is MongoDB Atlas Search?
Atlas Search is an embedded full-text search in MongoDB Atlas that gives you a seamless, scalable experience for building relevance-based app features. Built on Apache Lucene, Atlas Search eliminates the need to run a separate search system alongside your database.
Integrated Search in MongoDB Atlas
Easily build search on top of your data with an integrated, fully managed search engine that automatically syncs to your database.
Create Search Indexes
Create index definitions for your data using editors in the Atlas UI, with a single Atlas Admin API call, or using the Atlas CLI.
To learn more, see Atlas Search Index Definition
Construct Search Queries
Build and run Atlas Search queries using the $search
MongoDB aggregation pipeline stage.
To learn more, see Create and Run Atlas Search Queries.
Implement Best Practices
Refer to our guidelines on scaling and monitoring Atlas Search workloads.
To learn more, see Improve Atlas Search Performance.
Define Field Mappings
Index field values to run queries that use autocomplete, text, range, and other Atlas Search operators and collectors.
To learn more, see Data Types.
Pre-Process Data With Analyzers
Define how Atlas Search creates search terms using built-in analyzers or create your own.
To learn more, see Atlas Search Analyzers.
Add Synonyms for Search Terms
Configure synonyms to index and search collections for words that have the same or similar meanings.
To learn more, see Define Synonym Mappings in Your Atlas Search Index.
Build Complex Queries With Compound
Combine two or more operators and multiple clauses in a single search query using the compound operator.
To learn more, see How to Run Atlas Search Compound Queries with Weighted Fields.
Customize Relevance Scores
Modify the ranking of Atlas Search results to boost certain documents or match relevance requirements.
To learn more, see Score the Documents in the Results.
Filter and Parse Results Quickly
Use facets to group and count Atlas Search results by multiple categories.
