The performance of modern Question Answering Models (BERT, ALBERT ...) has seen drastic improvements within the last year enabling many new opportunities for accessing information more efficiently. However, those models are designed to find answers within rather small text passages. Haystack lets you scale QA models to large collections of documents! While QA is the focussed use case for Haystack, we will address further options around neural search in the future (re-ranking, most-similar search ...).
