But yes, the search function is in software in the viewer. I'm trying to think of an ebook format that wouldn't let you search it, and failing.

CBR/CBZ, the comic book formats. They're image-only; there's no searchable text.
I suppose some enterprising coder could make a comic/manga reader that would allow searchable metadata/text to be included, but creating that text wouldn't be nearly universal; it might happen for scanlations, but it's not likely for 150dpi comic book scans.
I've considered converting CBZ files to PDF by running them through FineReader so I can have a searchable collection, but the image quality is low enough that the OCR is atrocious; it basically requires hand-typing all of the text.
But other than "ebooks" that are just image collections, I think they're all searchable with the right software. (There might be some DRM setups that kill search along with printing, TTS, and display on unauthorized machines. I don't think that counts.)
