Thx for your answer. But the search is not very good. Lots of Genres aren't known and the results are often incorrect, e.g. genre:house -> why is there blondie in the search results??
User search: if I want to search for a special user (I have entered the name correctly), spotify cannot find any results for it. Why?
User searches are pretty flaky and only return a result 100% of the time if you know the user's spotify account name (it's actually a number). The full list of genres is in this table. Genres consisting of more than one word need to be enclosed in quotation marks when searrching. I have a HTML document here which might make things a bit easier.
