Do you have your settings set to allow Adult Content in searches? I had that issue for a while until I realised that by default Itch doesn't allow adult content games to show in searches.
I checked and yes I have it on, otherwise I wouldn't be able to find most FVN. Anyway, good thinking I suppose. Where I didn't have "allow adult content" active is Reddit, probably because I'm using a very good Reddit client for quite some time now. (Searching for OIHS works for some reason)
