In chrome, some search inputs might be mistakently treated as URLs/domains. To prevent that (or deliberately avoid visiting a domain, rather searching for it) you append a question mark before the search query (?google.com), so chrome treats it like a search query and looks up "google.com".
Orion, on the other end, looks up "?google.com" instead of just "google.com".
Expect it to look up "google.com" without the question mark.
