Rocker Johnny Hallyday was the person most searched for on Google in France in 2017, the US internet giant said Wednesday.

The singer, known as the French Elvis, was buried on the Caribbean island of Saint Barts on Monday two days after hundreds of thousands of fans lined the streets of Paris for his funeral.

And the most searched for song lyrics of the year was Hallyday's 1986 hit "Je te promets" (I Promise You).

The second most researched topic overall on Google was Maelys de Araujo, the eight-year-old girl who disappeared during a wedding reception in the foothills of the French Alps in August.

She has still not been found.

The UEFA Euro 2016 football championship was the most Googled subject the previous year, followed by the smartphone game Pokemon Go.
