Bug Report

Description

Bug Summary:
Extremely slow RAG when having 100+ documents.

Steps to Reproduce:

Upload 100 documents. (I used Docker docs in MD format)
Tag all with a common tag. (docker-docs or something make sense)
Ask question about docker with (#docker-docs)

Expected Behavior:
Finish RAG search in seconds

Actual Behavior:
Waiting 30 minutes+ for it to iterate every single collection

Environment

Open WebUI Version: 0.3.2
Ollama (if applicable): 0.1.39
Operating System: Linux Mint w/ Docker
Browser (if applicable): Firefox 126

Reproduction Details

Confirmation:

I have read and followed all the instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.

Logs and Screenshots

Browser Console Logs:
N/A

Docker Container Logs:

Installation Method

Additional Information

Discord Discussion

Alternative Solution

Manually concatenate all the documents into one single file to force it into a single collection.

Note

It is a design overlook more than a bug. The design of RAG doesn't consider scaling issue. For a complete set of documents, there isn't a need to have separate collections by each documents.
