TimeInterval is limited

[RobinE89]

I don't know the exact possibility but with a filter-setting of round around -300days there is only an error.
that means it is not possible to output a trend for a year+ - or for the full period (2004 to now -> called "ALL" in the google urn).

In combination with the missing worldwide statistics, the API can unfortunately only be used to a very limited extent. that's a shame because there are nearly no alternatives for php and the structure here is actually really great (especially because no login is necessary)!
