Haystack
Haystack is an open-source framework for constructing modular search and language-model pipelines.
How Building Reliable AI Systems covers it
- How deep it goes
- Names modular pipeline construction and production-ready components but provides no implementation details.
- How it connects
- Connects Haystack with retrieval-augmented generation, metadata filtering, LangChain, and LlamaIndex.

- retrieval-augmented generationuses · Retrieval-augmented generation is a technique that retrieves relevant information from external sources and supplies it as context to a generative model when producing an output.
- pipelineuses · A pipeline is an ordered or coordinated sequence of connected processing stages or tasks that passes data, work, or results toward an outcome.
- document databasehas part · A document database is a nonrelational database that stores and retrieves records as self-contained documents, often with flexible or nested structures.
- similarity searchuses · Similarity search is a retrieval technique that finds or ranks items by comparing their representations with a query according to a similarity or distance measure.
- context engineeringuses · Context engineering is the deliberate selection, organization, and management of information supplied to an AI system to support effective task performance.
