Google is trying fix a mysterious bug that returns pages and pages of almost exclusively pornographic and adult results when users enter certain equations or search strings.

A Google search for '-4(1/4)' at the time of writing revealed the result on a calculator, below which were several pages of porn links with titles such as 'four guys and a hooker' and others too lewd to repeat here.

According to the Age, other search strings that return mostly adult links included, '1 2'-1, '1 2' -2, 'h 3' -h, '1 4' -4 and 'apple 1' - apple.

The first person to notice the bug appears to be a poster on Quora who wondered what was causing this 'equation porn' when users search for contradictory queries.

Google search engineer Jeremy Hoffman said that firm was working on a ' bug fix'.
