A bug has been found on Google that causes certain queries to only return matches of pornographic nature, the use which some are calling an “Anti-Safesearch” feature.
This bug is caused when an “impossible” query is performed which contradict themselves, such as -2 “2 1”, which would only return results that include the phrase “2 1” but also filters out results with a 2 in them. As a result this brings up all kinds of adult content. Whilst these searches don’t cause adult results for every contradictory query, many do. Further examples of these queries are:
- -s “s 2″
- -3 “1 3″
- -4 “1 4″
- -title “title 4″
Be careful when searching these queries yourself, as previously stated they aren't something you’d want your boss or family to see!
Theoretically these searches should return 0 results. A bug fix is currently being worked on, as the bug is specifically causing Google to match adult content, as opposed to some sort of secret coding hidden in adult websites.
