Here's the first test search I did. "github ruby hanami" looking for the hanami github repo. Seems like a relatively simple query.
On Google, it's the first result. https://www.google.com/search?q=github+ruby+hanami
On mojeek, it's not even on the first page. https://www.mojeek.com/search?q=github+ruby+hanami
It's possible that at this point I (and others) have trained ourselves to know/do the kind of queries that work on Google, without even realizing it, which would be another thing making it hard to switch. Although in this case... I'm actually a bit surprised mojeek doesn't manage it. Just `github hanami` doesn't get it either. Is it just not matching on sitename at all?
