Search not working properly
a) Search is incredibly slow. For an exact match search string it takes often 20s+ to load results.
b) Search doesn't work for some short strings on web. I haven't experimented to find exact patterns but e.g. "ex" as a search string returns no results (this is expected as there is a three character minimum). But searching "ex:" misses many results including "ex:re" and includes results that shouldn't match (i.e. ones without the colon).
c) Likewise, search doesn't work correctly on the Android app. Here two character query strings are allowed. But a search for "ex:re" will not return the artist "ex:re". Again, I haven't experimented with all permutations where it doesn't work this is just one I have tested recently that isn't correct.
