public PlaceAutocompleteRequest offset(int offset) {
    return param("offset", String.valueOf(offset));
  }
The character position in the input term at which the service uses text for predictions. For
example, if the input is 'Googl' and the completion point is 3, the service will match on
'Goo'. The offset should generally be set to the position of the text caret. If no offset is
supplied, the service will use the entire term.

@param offset The character offset position of the user's cursor.
@return Returns this {@code PlaceAutocompleteRequest} for call chaining.
