Indexing Operations

Indexes allow MongoDB to process and fulfill queries quickly by creating small and efficient representations of the documents in a collection.

The documents in this section outline specific tasks related to building and maintaining indexes for data in MongoDB collections. For a conceptual overview of MongoDB indexing, see the Indexing Overview document. For strategies and practical approaches, see the Indexing Strategies document.
