I can't find myself through some of these searches, even when adding parts of my name in quotes. I wonder how fuzzy these results are, specifically from GitHub
Looks like the language search in GitHub only finds users where the majority of their repos are in a given language. If your repos are a mix of different languages then you won't appear in the search results it seems.
