Search algorithm different than imslp web

The (in-app purchase) extra annotation features make this exactly the app I would want--if I could only find the same search results from imslp that I get from a web search. No search results for William Tell, Sorcerers Apprentice. I assume (hope) the next release will adjust the search algorithm a bit to fix this.
