Bug Report

Installation Method

I install open-webui using docker without ollama

docker run -d -p 3000:8080 -v open-webui:/app/backend/data --name open-webui ghcr.io/open-webui/open-webui:main

And then install searxng using docker compose, docker-compose.yml is shown as below

version: "3.7"

services:
  redis:
    container_name: redis
    image: docker.1ms.run/valkey/valkey:8-alpine

Environment

  • Open WebUI Version: latest

  • Ollama (if applicable): not installed

  • Operating System: host: ubuntu22.04

  • Browser (if applicable): latest edge on Windows10

Confirmation:

  • [x ] I have read and followed all the instructions provided in the README.md.
  • [ x] I am on the latest version of both Open WebUI and Ollama.
  • [x ] I have included the Docker container logs.
  • [x ] I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Behavior:

Firstly, it comes out "Error searching "

Image

the logs show that the query string is empty

Traceback (most recent call last):

log of searxng:

after several tries, it comes out "No search query generated", and there are no logs from open-webui or searxng

This happens when the reponse generated by the LLM isn't correctly formatted as required by the web search (should be an array of queries). This error depends on the model used and its ability to respect its system prompt.

I am having this exact issue and continue to get this error message (even though it will show that it received three search results):

SyntaxError: The string did not match the expected pattern.

I had no issues until after 5.9. I have no idea what go broken but it is definitely on OpenWebUI’s side and not Searxng because I have tested the API outside of OpenWebUI without issue.

Also here. However, I could not confirm whether SearXNG or Open WebUI goes wrong. If I run http://searxng:8080/search?q=hello&format=json, it returns:

{
  "query": "hello",
  "number_of_results": 0,
  "results": [
    {
      "title": "HELLO | English meaning - Cambridge Dictionary",
      "url": "https://dictionary.cambridge.org/dictionary/english/hello",
      "content": "Learn the meaning and usage of the word hello in English, with synonyms, pronunciation, and translations. Find out how to say hello in different situations, such as greeting someone, answering the phone, or attracting attention.",
      "engine": "duckduckgo",
      "template": "default.html",
      "parsed_url": [
        "https",
        "dictionary.cambridge.org",
        "/dictionary/english/hello",
        "",
        "",
        ""
      ],
...

It's weird because there are exactly some results while number_of_results is 0. But it seems not to be a fatal bug as https://github.com/searxng/searxng/issues/2457 just discussed.
My Open WebUI and SearXNG docker instances run on WSL2. Expecting for any helpful fixes or anwsers.
