You can specify which fields to include in the response:
vector: The vector data itself
contents: Content associated with the vector (always returned as bytes/Buffer)
metadata: Structured metadata object
The contents field is always returned as bytes (Python), Buffer (JavaScript/TypeScript), or []byte (Go), regardless of whether it was originally stored as a string or bytes. All contents are encoded to bytes and encrypted before storage.
If you don’t specify include, the default is ["vector", "contents", "metadata"].
