Haystack v3.3.0 reduces Document Store calls for faster retrieval.

The official source reports this update: v3.3.0. ⭐️ Highlight ⚡️ Faster SentenceWindowRetriever SentenceWindowRetriever now queries the Document Store once per run or run_async call instead of once per retrieved document. Fewer calls mean lower latency and less load on the Document Store and outputs have not changed, so existing pipelines get faster without code changes. ⬆️ Upgrade Notes InMemoryDocumentStore.bm25_retrieval and InMemoryBM25Retriever with BM25L (the default) or BM25Plus now return only documents that contain at least one query term, with or without scale_score . Previously, documents without any query term were returned with a positive score and filled up top_k .
