Sometimes, you’re not just searching for something—you know exactly which vector you want to retrieve.

In such cases, you can directly fetch specific vectors from your database.

​
Fetch

Each record in Upstash Vector is assigned a unique ID, which you can use to retrieve a specific vector from your database.

Let’s use the fetch() method to retrieve a vector from Upstash Vector.

use Upstash\Vector\Index;
use Upstash\Vector\VectorFetch;

$index = new Index(
  url: "<UPSTASH_VECTOR_REST_URL>",
  token: "<UPSTASH_VECTOR_REST_TOKEN>",
);

$results = $index->fetch(new VectorFetch(
  ids: ['1', '2'],
  includeMetadata: true, // (optional) if true the fetch results will contain metadata.
  includeVectors: true, // (optional) if true the fetch results will contain the indexed vectors.
  includeData: true, // (optional) if true the fetch results will contain the string data.
));

The fetch() method returns a Upstash\Vector\VectorFetchResult object, which allows you to access the results of the query.
