It seems odd that there seem to be no iOS apps that do this simple thing that even lowly Kindles do. I suppose it is just too easy to do in memory searches, and that adding a persistent index of all downloaded content seems like a lot of work that almost nobody would appreciate.
It would be relatively trivial to add book metadata to app index to make that content searchable with Spotlight but it would not solve this more general use case.
I think developers of BookFusion could justify adding such a feature, especially if it were tied to a paid subscription (which can be as little as $19/yr). They update the app frequently, and have an Android app too.
