Search becomes useless if you drown in results. A good organization should assist in shortening paths, but if you start the path manually or through a search doesn't matter much.
Using a hybrid of traditional and semantic is so trivial to implement these days that I think we have past the point of needing good organization.
Maybe if you are Google, having well paid teams and excessive data on what people with your profile are usually searching at the moment. Obsidian is lacking all this, so the search-quality is very depending on the amount of files and results.
