Haystack: The State of Search in 2021

The Haystack project aims to build a semantic search engine that can adapt to user information needs and way of speaking, moving beyond keyword-based systems. By incorporating state-of-the-art NLP methods, such as retriever-reader pipelines, answer generators, summarizers, and flexible pipelines, Haystack enables developers to create bespoke natural language interfaces into text data. The project's goal is to provide a more efficient and accurate search experience, allowing users to ask complex full-sentence questions and receive curated responses. With ongoing research and development, Haystack plans to incorporate multilingual and domain-specific language technologies, further expanding its capabilities.
