I've configured a .ppignore file that includes *.raf (Fujifilm RAW files) and *.dng (RAW files from my Android phones). I would expect those files to be ignored when indexing, but it seems the process that finds related files (files with the same name in the same directory with different extensions) still finds and stacks these ignored files.

I know I could put the raw files in a different directory, but I use the auto-transfer feature on my camera that puts all new RAW and jpeg files into a directory on my computer (which is indexed by photoprism). I would have to quickly move the files before the index runs or manually copy over the files via USB.

I suggest a setting that enables more strict adherence to the .ppignore configuration, so that ignored files are ignored at all parts of indexing - including stacking.

This could possibly be a problem if someone added *.jpg to their .ppignore file, but considering that .ppignore needs to be manually created already means it's a "continue at your own risk" kind of thing. If it was a text field in the web GUI, it would be a lot more dangerous.
