Start in var/search/selenium_search.py at get_urls line 72 and inspect how the random dork from the log is decoded. Reproduce with `zeus.py -r -W -E` and the shown query, then check parse_search_results around line 268. Done means this input no longer produces the reported UnicodeDecodeError or an unhandled search failure.
