I believe that in the example suggested by David, and in your's, if it it similar, you will get even better performance if you use the between() statement. I suggest you try it. If it does, indeed, work faster, I will explain why.

Make sure you do NOT have an index on deleted(). Or at least, test with, and without, one.
