If an `offset` is defined, the decay function will only compute a the
decay function for documents with a distance greater that the defined
`offset`. The default is 0.

The `decay` parameter defines how documents are scored at the distance
given at `scale`. If no `decay` is defined, documents at the distance
`scale` will be scored 0.5.
