Hmm, let's see. Advanced Searches are still available in our Search. You can filter your search results further by using the filters on the left-hand side of 'http://soundcloud.com/search' These options allow you to filter sounds by upload date, length, license, or tags (tags and genres are actually treated equally here.
Our search relies on an algorithm called ‘Discoranking’ (which stands for “Discovery Ranking”) which returns the most popular results first. Discoranking pulls the search results based upon a variety of variables including the wording of your search and the popularity of profiles.
Each track and artist has a "DiscoRank" that is calculated by a wide variety of factors. These factors include, but are not limited to; the number of likes, reposts, and followers associated with specific tracks and accounts. Not only does the number of your own followers give you a higher DiscoRank-- we also consider how many followers your followers have and so on. The more “influential” the network of followers you are associated with, the higher your DiscoRank will be. As you can imagine, this network could go on forever!
All of these factors work together to give the most popular and relevant results for a search. For example, even if you input an exact Profile URL into search, there may be profiles which have a wider network of popularity which will rank higher than an exact word match. Same goes with the genre term - having it in the search field doesn't limit our search engine to search for only tracks that have this term in their title.
It is important to note that an account’s Display Name is just one of many variables which affect your position within search results; your popularity remains the dominant factor in Discoranking algorithms. Therefore, the fact that more than one account can now have the same Display Name will have no impact on search results.
I hope this allows you to understand the search results you're seeing more comprehensively. Please let us know if you have any other questions or concerns.
