Qdrant + JS / How to return vector embedding?

Question

I am learning Qdrant through this repository: https://github.com/qdrant/qdrant-js/blob/master/examples/node-js-basic/index.js

And I have a problem with the return vector. I am using this code.

const res1 = await client.search(collectionName, {
        vector: queryVector,
        limit: 3,
    });

    console.log('search result: ', res1);
    // prints:
    // search result:  [
    // {
    //     id: 4,
    //     version: 3,
    //     score: 0.99248314,
    //     payload: { city: [Array] },
    //     vector: null
    // },

Even in the documentation, the vector is null. I added an embedding and inserted several records. The similar search is working great, but I am thinking about how to access the embedding that is stored in the vector.

Qdrant does not return stored vectors for retrieval methods by default.

You can enable this with the with_vector parameter.

const res1 = await client.search(collectionName, {
    vector: queryVector,
    limit: 3,
    with_vector: true,
});
