At around 1:30 into the movie Lion, Saroo tears his schedules from the wall, then starts clicking Google Earth more or less at random. He then moves out of his original search radius - the Google Earth shots suggest only in the order of kilometers - and then notices a characteristic surface structure that draws his attention. Ultimately that leads to the answer of his search.
At this point in the movie I had serious issues maintaining my suspension of disbelief.
I can understand that in desperation he would click outside of the area he had already searched. But that would assume that the direction of his original searches was correct (based on something he 'knew'?). It would also imply that he used the correct amount of zoom to recognize an area that he has not seen from the air before.
Since the movie is based on a real story, this makes me wonder:
Did Saroo find the actual location based on more factual information or clues than presented in the movie?
