Application search simplified

With Atlas Search, you can create a search index on your data in a few clicks or single API call. Test queries and preview results to fine-tune relevance before deploying them in application code.

Made for MongoDB Atlas

Work faster and smarter. Because you can build search directly in Atlas, there’s no need to replicate your data anywhere else – and you don’t need to set up, maintain, or scale a separate search platform.
