My Question or Issue

In classical music track title often contains catalogue number (RV, HWV, K, BWV, etc).
But if I try to search something unpopular "RV 470" or "RV 274" on android get the irrelevant result (look likes fuzzy matching), while search result on desktop is more accurate. When I search something extremely popular like "BWV 565" the result is OK
