Omni search cannot find some of my PDFs

Hi,
I'm super new to Obsidian and computer stuff in general so I don't have a ton of knowledge on this issue.

I recently set up an obsidian vault to organize all of my Notes and references for my manual therapy practice. My hope is to be able to search these notes for a certain trigger points and body areas to get results on everything that might be related to certain issues. Essentially trying to be able to reference material quickly and reliably.

I uploaded all of the books as OCR PDFs, but when I use Omni search, only some of them are referenced an index by that search. I've tried restarting, clearing the cash, turning off all other plug-ins, but nothing seems to work.

Any ideas?

Text Extractor can take a long time to extract text, depending on the size and number of files. The result is cached after that, but that's a long process.

To check if a file is ok, you can right click on it, select "Text Extractor", and check the extracted text. If you get an empty result, that means Text Extractor failed to work on that particular file.

How long of a process we talking? Its been a few days I've has the vault open with text extractor and Omnisearch.

When I right click, my only option are "extract text to clipboard" or "extract text to new note" and clear cache.

When I right click on the specific PDFs, it does highlight the text which would show it is recognizing the text, but when I use omni search it still does not show up.

It is one whole folder that I uploaded together that does seem to work, while the other folders I uploaded don't. I didn't do anything different in the process, but I wonder why one book is searchable while the others are not.

Sorry I missed that part. PDFs are not OCRed by Text Extrator, they're just read as-is to try and get their textual content. Only image files are OCRed. So it's normal that most of your books cannot be indexed.

As for the time it can take, Text Extractor will work on a file for at most 2 minutes before giving up, and that time can be too short for a whole book.
