I needed this urgently for indexing PDFs as Spotlight on the Mac is highly erratic after all this years.
Anything LLM seemed the most promising approach with an easy to use GUI and being well documented. But indexing failed after several hours, so I went on with LM Studio. Also this installation turned out to be more complicated than expected due to library “dependency hell” and version mismatch spiralling…
- Download and install LM Studio
- From inside LM Studio download your preferred model
- Index your PDFs in batches of 1,000 using the Python script below
- Combine indices and run queries against the full index
30.000 PDFs result in a 4G index while the system is unfortunately not very responsive (yet)
