Is there a way to search Fediverse? - Lemmy.world

Hi! Sorry if this is a common question. Is there a tool, search engine or methods so search for a given topic or posts on Fediverse (lemmy, kbin, mastadon, etc)? I come across a lot of great discussions and posts. It would be great to find more about a specific things, or even debugger a problem. Kind of like appending reddit to your Google search to find a niche discussion or solution.
