Another thing on the subject I noticed is:
For some phrases it will report the aggregate search volume, thus equal s.v. for the singular and plural. e.g. tel aviv hostels and tel aviv hostel show each a s.v. of 1300.
But "Jerusalem hostel" (s.v. reported - 880) and "Jerusalem hostels" (170) don't!!!
So W.T.F. Google trying to do here? Make us realize that they really really don't want us to use k.w.p. data? First take away the broad s.v. data leaving only the lesser valuable data of the exact, then having the bucket aggregation .... What's next? Don't they want us to show the true potential in Google searches to digital marketing clients??? Kind of hard when you have to either give false inflated numbers and say that there is no true accurate number these are all estimates that might even be very far from the real numbers.
