Searching iOS App with exact name

My app name is Rainbo, its in shopping category, and when I search in App Store with exact name, the result number is 208, which makes it very difficult for me to market the app. Its literally not possible for anyone to scroll down to 208 and figure out the app. I understand that there will be some logic and algorithms used for app searches, but searching with the exact app name should be given the highest priority right? And that too App Store has unique app names. I understand if the search term is a generic word like shopping, product etc, the search results can vary depending on the search metadata, rankings and other algorithms. My same app in Play Store list as first item when I search with Rainbo keyword, even though Play Store app names are not unique. I hope you will look in this issue seriously, as it is impacting my business severely.
