Flexibly accommodate any data type

The MongoDB Query API is purpose-built to handle data of any structure. Quickly query, transform, and analyze data as
your schema evolves.

Efficiently handle key tasks —
in one place

Execute key data operations, including indexing, querying, and updating, directly from the MongoDB Query API. No need to switch between interfaces or query syntax.

Simplify the development process

Query and aggregate data using your preferred coding language. The MongoDB Query API includes drivers to programmatically generate queries and build aggregation pipelines— removing the need to learn a new query language
from scratch.

Feature overview

Query and update

Use powerful operators like $updateMany and $set to query and update documents in a collection.

Diverse index types

Optimize your queries with many index types — no matter how deeply nested the fields.

Transform + analyze data in place

Create real-time analytics against live data in the same cluster — no ETL or duplication needed.

Full-text search built for the document model

Deploy advanced, full-text search — without the need to manage additional infrastructure.

Change streams

Build real-time, event-driven apps that react to database changes by triggering server-side logic.

Join and union

Use $lookup and $unionWith to join and blend multiple collections for deep analysis and exploration.

Geospatial and graph data

Easily query geospatial data and use operators like $graphLookup to traverse connected data sets

On-demand materialized views

Pre-compute and cache common queries, dynamically updating result sets as new data is processed.

Seamlessly work
with data

Tap into the MongoDB Query API to work with your data in a native, familiar way. Run queries, build complex aggregation pipelines, and power applications — using the language you prefer.
