Haystack is an open-source framework for building search systems that work intelligently over large document collections.
You load your own documents (Text, PDF, DOCX) and haystack applies the latest NLP transformer technology to allow you to perform natural language searches across your document store.
The demo takes its data from a selection of Wikipedia pages crawled in November 2021 on the topic of countries and capital cities. Ask any question on this topic and see if Haystack can find the correct answer to your query!
Note: do not use keywords, but full-fledged questions. The demo is not optimized to deal with keyword queries and might misunderstand you.
