As we analyze zero-result queries in the request logs, we sometimes identify high-volume patterns of requests.
For these cases, we want to try to track down the originator of the queries to understand what they are trying to do, and how we can help them make their queries more successful.
Research may include digging through web and app logs, and may include contacting the originators of the requests to get clarification of their intent. Contact could be through email, github issues, etc. (We aren't looking for individuals, but rather apps, other software, or websites that automatically create searches that fail in high volumes.)
