 Now, thanks to the new batch search, you don’t need to worry about that. Qdrant will handle multiple search requests in just one API call and will perform those requests in the most optimal way.

 We’ve used the official Python client to show how the batch search might be integrated with your application. Since there have been some changes in the interfaces of Qdrant 0.10.0, we’ll go step by step.

 Now we’re ready to start looking for similar vectors, as our collection has some entries. Let’s say we want to find the distance between the selected vector and the most similar database entry and at the same time find the two most similar objects for a different vector query. Up till 0.9, we would need to call the API twice. Now, we can send both requests together:

 In order to do that, we’ll create a richer collection of points, with vectors from the *glove-25-angular* dataset, quite a common choice for ANN comparison.

 Additional improvements could be achieved in the case of distributed deployment, as Qdrant won’t need to make extensive inter-cluster requests. Moreover, if your requests share the same filtering condition, the query optimizer would be able to reuse it among batch requests.

 Batch search allows packing different queries into a single API call and retrieving the results in a single response. If you ever struggled with sending several consecutive queries into Qdrant, then you can easily switch to the new batch search method and simplify your application code. As shown in the benchmarks, that may almost effortlessly speed up your interactions with Qdrant even by over 30%, even not considering the spare network overhead and possible reuse of filters!
