企业语义搜索
使用模块化检索器、嵌入器和文档存储创建可投入生产的语义搜索系统，以在大型数据集中提取相关信息。
问答系统
实施问答工作流程，从内部知识库、技术文档或客户支持内容中提取或生成答案。
具有工具调用的 LLM 代理
构建基于代理的应用程序，利用 Haystack 的工具调用能力执行多步骤推理，并与外部 API 和服务交互。

Does the job
Pretty happy overall. Retrieval-augmented generation support just works and modular pipeline design for flexibility. Steeper learning curve for beginners can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.
Compared a few options
Evaluated this against two competitors. Where it wins: document store and retriever components and active community and detailed documentation. On balance the feature set — especially agent and tool-calling capabilities — justifies the 5 stars for our use case.
Solid for our team
We rolled this out across the team last quarter and fully open-source and self-hostable. Retrieval-augmented generation support fits neatly into how we already work, and composable pipelines for LLM workflows removed a step we used to do by hand. Steeper learning curve for beginners, which is the main caveat, but it has held up under daily use.
Compared a few options
Evaluated this against two competitors. Where it wins: integrations with major vector databases and strong support for RAG and semantic search. Where it lags: steeper learning curve for beginners. On balance the feature set — especially retrieval-augmented generation support — justifies the 4 stars for our use case.
Use it every day
Honestly didn't expect to like it this much. Document store and retriever components is exactly what I needed, and fully open-source and self-hostable. I do wish requires Python and infrastructure setup, but I reach for it almost every day now and it just clicks.
