What is Haystack?

Haystack is an open-source framework for building search systems that work intelligently over large document collections. It excels at question answering, semantic document search, and retrieval-augmented generation (RAG). It provides modular components for tasks like document cleaning, indexing, retrieval, and question answering, allowing developers to create customized search pipelines. Common use cases include building chatbots that answer questions based on internal company documents, creating search engines for research papers, and automating information extraction from large datasets.
