description Haystack Overview
Haystack is a modular framework for building production-ready search and QA systems. It focuses on creating pipelines where components (retrievers, rankers, generators) can be swapped out easily. Its architecture is highly structured, making it an excellent choice for enterprise environments where predictability and maintainability are paramount. Haystack provides deep support for various retrieval techniques and integrates well with a wide array of search engines.
help Haystack FAQ
What is Haystack used to build?
Haystack is a framework for building search, question-answering, and retrieval-augmented generation systems. It lets developers connect components such as document stores, retrievers, rankers, and language models into pipelines.
Can I replace the retriever or language model in a Haystack pipeline?
Yes. Swappable components are a central part of Haystack's design, so a team can change a retriever, ranker, generator, or document store without rewriting the whole application.
Is Haystack only for keyword search?
No. It can support semantic retrieval and question answering with embedding models and language models as well as more traditional search components. The chosen pipeline determines how results are retrieved and generated.
Is Haystack suitable for production applications?
It is designed for structured, production-oriented pipelines rather than only notebook experiments. Teams should still add their own evaluation, access controls, monitoring, and data-quality checks before deploying a system.
