Range

Method

The range method allows you to retrieve vectors from the index within a specified range. The function accepts the following parameters:

• cursor: A cursor to start the range query.
• prefix: A string prefix to match vector IDs. All vectors with IDs that start with this prefix will be retrieved.
• limit: The maximum number of vectors to retrieve in a single query.
• include_vectors: A boolean flag indicating whether to include vectors in the range results.
• include_metadata: A boolean flag indicating whether to include metadata in the range results.
• include_data: A boolean flag indicating whether to include data in the range results.

As response, the object has the following fields:

• next_cursor: A cursor indicating the position to start the next range query. If "", there are no more results.
• vectors: A list containing information for each vector, including id, vector, and metadata.

Range Example

from upstash_vector import Indexindex = Index.from_env()# Execute the range queryrange_result = index.range(    cursor="",    limit=10,    include_vectors=False,    include_metadata=True,    include_data=True,)# Print the range resultprint("Next Cursor:", range_result.next_cursor)for vector_info in range_result.vectors:    print("ID:", vector_info.id)    print("Vector:", vector_info.vector)    print("Metadata:", vector_info.metadata)    print("Data:", vector_info.data)

Range with id prefix

This will retrieve all vectors with IDs that start with the prefix.

index.range(prefix="id-")

Scanning Whole Index

For scanning the entire index, you can use a similar loop as shown below:

res = index.range(cursor="", limit=5)print(res.vectors)while res.next_cursor != "":    res = index.range(cursor=res.next_cursor, limit=10)    print(res.vectors)

Also, you can specify a namespace to operate on. When no namespace is provided, the default namespace will be used.

index.range(..., namespace="ns")
