I've found AR reader search compatibility to be a mixed bag. Some ebook producers, like those using EPUB3 standards, have integrated AR features seamlessly, allowing for interactive elements and enhanced searchability. However, many smaller publishers or older ebook formats still lag behind, making AR search functionality inconsistent.
I’ve noticed that platforms like Kindle and Kobo are gradually improving AR support, but it’s not universal. For instance, textbooks or graphic novels with AR components often work better on dedicated apps like 'Apple Books' or 'Google Play Books,' while plain-text novels might not benefit as much. The key takeaway is that compatibility depends heavily on the producer’s tech stack and the reader’s device. If you’re into AR-enhanced reading, sticking to major publishers or newer releases is your best bet.
