Is the C++ API Documentation down?

Just wanted to read something again in the C++ API Docs but all my searches end with no results?

Even if I don’t use a filter no results are shown, also for the Blueprints API and Python API.

Am I stupid or does it seem like there are problems right now? xD

Everything else seems to work, but the APIs do not. Have they been moved somehow or what’s going on?

Okey if I search with prefix and no filter at least the right results are shown, seems to be a bug in the filter
