Query: Rapidly Deploying a Neural Search Engine for the COVID-19 Open Research
  Dataset: Preliminary Thoughts and Lessons Learned   We present the Neural Covidex, a search engine that exploits the latest
neural ranking architectures to provide information access to the COVID-19 Open
Research Dataset curated by the Allen Institute for AI. This web application
exists as part of a suite of tools that we have developed over the past few
weeks to help domain experts tackle the ongoing global pandemic. We hope that
improved information access capabilities to the scientific literature can
inform evidence-based decision making and insight generation. This paper
describes our initial efforts and offers a few thoughts about lessons we have
learned along the way.
