A French anti-racism group is taking on internet giant Google over its "auto-complete" function.

When internet users type in certain famous names, including media mogul Rupert Murdoch or Jon Hamm or Mad Men fame, the search engine recommends that the next keyword be "Jewish".

According to the Hollywood Reporter, SOS Racisme and other similar organisations are now taking legal action to try and prevent what it views as a discriminatory practice from continuing.

A hearing will take place on Wednesday, with the plaintiffs complaining that Google is "overseeing the creation of what is probably the biggest Jewish file in history". They said that this violates a French prohibition on collecting files about individuals based on their ethnicity.

The lawsuit states: "Numerous users of the first search engine of France and the world are confronted daily with the association, unsolicited and almost systematically, [of] the word 'Jew' with the names of those most prominent in the world of politics, media or business."

According to Google, "queries in auto-complete are algorithmically determined based on a number of factors (including search term popularity) without manual intervention."

Last year SOS Racisme successfully forced Apple in France to remove an app called "Jew or Not Jew", accusing the developer of violating French law.
