For example: If I start to drill down through the grouping and go to title, and then select and hold the "M" it asks me how do I want to match the books. If I say "Matching" it instantly goes back to the top level and says it found 364 books and the search shows "title:~^M" If I change the "M" to an "R", it scans through the books one at a time looking for matches and takes about 20 seconds to find the matching books.

Are you doing something different in the search that matches so quickly or am I doing something wrong in the searching syntax. Because if there really is no way to do a manual search that take less time on large libraries, it might be worth adding an option to disable all of the searching and the search box. Frankly, it might even be worth making that the default to cut down on confusion for new users.
