Lately I've been having problems with my Kindle Fire HD with regards to various search and history features that seem to be related to the Kindle's index and I've been struggling to find a fix.

One issue is that the search index for some of my books seems to be broken. Only some of the instances of a word are listed in the search results, rather than results from the entire book. One specific example is that one long ongoing webnovel (1200+ chapters) only returns results from the final 50 chapters. Searching was fine for the original book I uploaded, but seems to have broken after I uploaded an updated version with more chapters. The book itself shouldn't be corrupted since opening it up in Calibre ran into no problems, the bug check didn't find any problems, and search results are correct in the Calibre internal viewer. I tried forcing the Kindle to re-index the book by deleting it, rebooting the Kindle, then reuploading it, but somehow the Kindle remembered my previous interactions with the book through the reboot/reupload.

The other issue started up a few months ago where now my Kindle resets all book statuses as "New" in the library/carousel every time I upload a new book through Calibre. The Kindle still remembers my progress in each book when I click into each book, but the library/carousel completely loses track of which books I read last prior to the new uploaded books and instead orders all my books by upload time when sorting by "Most Recent".

Anyone have any advice on what I should do? I am willing to do a factory reset as a last resort, but I'd like to know if there's a less drastic fix I should try.
