It's pretty telling when you search "bar" or something in a given area and the most commercial places pop up with icons and names, obscuring a sea of minor red dots that are also in fact bars. And moving the map tiles doesn't automatically research either. Unless you thoroughly scrubbed an area, searching and researching for "bar" every half dozen blocks, you are only going to gleam a small % of the places in that area.
At least they haven't brought this corporatism to google earth desktop yet. I can pull up on the map every single bar and restaurant in Los Angeles in one search if I wanted to.
