queryVectors

Amazon S3 Vectors is in preview release for Amazon S3 and is subject to change.

Performs an approximate nearest neighbor search query in a vector index using a query vector. By default, it returns the keys of approximate nearest neighbors. You can optionally include the computed distance (between the query vector and each vector in the response), the vector data, and metadata of each vector in the response.

To specify the vector index, you can either use both the vector bucket name and the vector index name, or use the vector index Amazon Resource Name (ARN).

Permissions

You must have the s3vectors:QueryVectors permission to use this operation. Additional permissions are required based on the request parameters you specify:

• With only s3vectors:QueryVectors permission, you can retrieve vector keys of approximate nearest neighbors and computed distances between these vectors. This permission is sufficient only when you don't set any metadata filters and don't request vector data or metadata (by keeping the returnMetadata parameter set to false or not specified).

• If you specify a metadata filter or set returnMetadata to true, you must have both s3vectors:QueryVectors and s3vectors:GetVectors permissions. The request fails with a 403 Forbidden error if you request metadata filtering, vector data, or metadata without the s3vectors:GetVectors permission.
