This is the example from demo site:
I searched "Rind 2002" in films. Most actual "Lord of Ring 2002"

This is the result:
0) Cidade de Deus (2002) - (0.35)

1. The Lord of the Rings: The Fellowship of the Ring (2001) - (0.27)
2. The Lord of the Rings: The Two Towers (2002) - (0.27)

It's because in the first film title tokens count lesser the others (Lord of Rings longer then Cidade de Deus)
And in this way "Ring" more important then 2002 (May be)
