Is it possible to run multiple queries in a query pipeline in Haystack version >2.0 ?

[kathy-lee]

Hi all,
I'm a beginner in Haystack :) May I ask in this tutorial sentencetransformerstextembedder in pipeline, is it possible to run the pipeline with multiple queries at once? By which I mean the following run of the pipeline in this tutorial:

result = query_pipeline.run({"text_embedder":{"text": query}})

I see 'run_batch' feature, but seems it was in Haystack version < 2.0.
And I see in the __init__() interface of class SentenceTransformersTextEmbedder there is a parameter batch_size: int = 32, but I'm not sure if it's exactly what I'm looking for, and I could not find a tutorial with its usage either.

Thanks for any help!
