Currently when a user searches for something in the app they'll see a list of results relevant to their search term. Concurrently in your analytics you'll see a search event with an attached dimension of what the user has searched for, but nothing about the number of results returned.
We know how many results each term returns, but as of now we don't have a way of telling the user or you. We intend to present this at the top of the search page and add it as a dimension to search events.
