Why do some queries take a long time to finish, or in the end yield no results?

In the alpha phase, part of our tasks is to optimize the system. In the beginning, one may expect some actions to take an inordinate amount of time, but this is getting better and better. If you notice a persistent failure in some specific case, please be so kind as to let us know.

I want to report an issue, how do I do it?

Please refer to our public ticketing system for the frontend at GitHub to report on any issues. If you don't have a GitHub account, please send us an e-mail.
