Osmand doesn’t appear to be able to locate street addresses. Like if I input something like “123 4th Street” all it can do is offer some cross streets, which may be miles away from my intended location.
Is there a way to augment it’s data so street addresses work? Maybe there’s a service I can add?
Similarly, it doesn’t know the names of many businesses.
If it can’t find it, it’s because it’s probably not in OpenStreetMap. Same thing for businesses. It’s our collective responsibility to fill those gaps as a community!
So start editing your local map on OpenStreetMap.org, you can also join local communities that will help you out on your doubts.
