I'll admit this is not a huge deal, but I'm curious.
If I open the library and begin a search for title (title:), before I type any text after the colon, about 98.7% of my books are filtered out, showing 1.3%. All of these books, of course, have a title. (There seems to be no relevance as to whether they have a short title or not.)
My question is this: What is the library filter responding to by showing books when I enter the following line?
title:
I will add that it works similarly if I have another filter component, such as
mytag:#ReadLater
Thanks!
