Code search tool, like GitHub Copilot, that is open to all now?

I looked at https://about.sourcegraph.com/ but it seems...difficult, or just doesn't work for what i want, or similar.

What do i want?

javascript code that searches a tree (Chrome bookmarks) and returns the Nth+ leaf node that is not a folder, not a javascript: or data: URL, and return that node/bookmark and its 'N' value.

...and searchcode.com reports "There was an error processing your search. Please try a new search term."
