I have an new iOS app called CaptionEdit. I have set a number of different keywords for it in App Store Connect including 'caption photos' and 'add text to photos'. However, if I type either of these these phrases into the iOS App Store search box, my app does not appear in the 150+ results at all, even though the bottom-ranking apps (like mine) have no ratings or reviews. App Store connect indicates that my app has had 29 downloads over the past month and 5 over the past 7 days. Is the absence of my app in search results from a keyword due to apps requiring a minimum number of downloads over an averaging period to even appear in keyword search results? (The app does appear if use the app name as a search term).

There is some Algorithm behind. Nobody tells you how it exactly works. But downloads, revenue and reviews make a difference.
Just be happy if it appears when you search for the exact app name :)
