🌐 Web Search​

This guide provides instructions on how to set up web search capabilities in Open WebUI using various search engines.

SearXNG (Docker)​

"SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled."

1. SearXNG Configuration​

To configure SearXNG optimally for use with Open WebUI, follow these steps:

Step 1: git clone SearXNG Docker and navigate to the folder:

  1. Create a New Directory searxng-docker

Clone the searxng-docker repository. This folder will contain your SearXNG configuration files. Refer to the SearXNG documentation for configuration instructions.

git clone https://github.com/searxng/searxng-docker.git

Navigate to the searxng-docker repository:

cd searxng-docker

Step 2: Locate and and modify the .env file:

  1. Uncomment SEARXNG_HOSTNAME from the .env file and set it accordingly:
# By default listen on https://localhost
# To change this:
# * uncomment SEARXNG_HOSTNAME, and replace <host> by the SearXNG hostname
# * uncomment LETSENCRYPT_EMAIL, and replace <email> by your email (require to create a Let's Encrypt certificate)

SEARXNG_HOSTNAME=localhost:8080/
# LETSENCRYPT_EMAIL=<email>

# Optional:
# If you run a very small or a very large instance, you might want to change the amount of used uwsgi workers and threads per worker
# More workers (= processes) means that more search requests can be handled at the same time, but it also causes more resource usage

# SEARXNG_UWSGI_WORKERS=4
# SEARXNG_UWSGI_THREADS=4

Step 3: Modify the docker-compose.yaml file

  1. Remove the localhost restriction by modifying the docker-compose.yaml file:
sed -i "s/127.0.0.1:8080/0.0.0.0:8080/"

Step 4: Grant Necessary Permissions

  1. Allow the container to create new config files by running the following command in the root directory:
sudo chmod a+rwx searxng-docker/searxng

Step 5: Create a Non-Restrictive limiter.toml File

  1. Create a non-restrictive searxng-docker/searxng/limiter.toml config file:
searxng-docker/searxng/limiter.toml
# This configuration file updates the default configuration file
# See https://github.com/searxng/searxng/blob/master/searx/botdetection/limiter.toml

[botdetection.ip_limit]
# activate link_token method in the ip_limit method
link_token = false

[botdetection.ip_lists]
block_ip = []
pass_ip = []

Step 6: Remove the Default settings.yml File

  1. Delete the default searxng-docker/searxng/settings.yml file if it exists, as it will be regenerated on the first launch of SearXNG:
rm searxng-docker/searxng/settings.yml

Step 7: Create a Fresh settings.yml File

note

On the first run, you must remove cap_drop: - ALL from the docker-compose.yaml file for the searxng service to successfully create /etc/searxng/uwsgi.ini. This is necessary because the cap_drop: - ALL directive removes all capabilities, including those required for the creation of the uwsgi.ini file. After the first run, you should re-add cap_drop: - ALL to the docker-compose.yaml file for security reasons.

  1. Bring up the container momentarily to generate a fresh settings.yml file:
docker compose up -d ; sleep 10 ; docker compose down

Step 8: Add Formats and Update Port Number

  1. Add HTML and JSON formats to the searxng-docker/searxng/settings.yml file:
sed -i 's/formats: \[\"html\"\/]/formats: [\"html\", \"json\"]/' searxng-docker/searxng/settings.yml

Generate a secret key for your SearXNG instance:

sed -i "s|ultrasecretkey|$(openssl rand -hex 32)|g" searxng-docker/searxng/settings.yml

Windows users can use the following powershell script to generate the secret key:

$randomBytes = New-Object byte[] 32
(New-Object Security.Cryptography.RNGCryptoServiceProvider).GetBytes($randomBytes)
$secretKey = -join ($randomBytes | ForEach-Object { "{0:x2}" -f $_ })
(Get-Content searxng-docker/searxng/settings.yml) -replace 'ultrasecretkey', $secretKey | Set-Content searxng-docker/searxng/settings.yml

Update the port number in the server section to match the one you set earlier (in this case, 8080):

sed -i 's/port: 8080/port: 8080/' searxng-docker/searxng/settings.yml

Change the bind_address as desired:

sed -i 's/bind_address: "0.0.0.0"/bind_address: "127.0.0.1"/' searxng-docker/searxng/settings.yml

Configuration Files​

searxng-docker/searxng/settings.yml (Extract)​

The default settings.yml file contains many engine settings. Below is an extract of what the default settings.yml file might look like:

searxng-docker/searxng/settings.yml
# see https://docs.searxng.org/admin/settings/settings.html#settings-use-default-settings
use_default_settings: true

server:
  # base_url is defined in the SEARXNG_BASE_URL environment variable, see .env and docker-compose.yml
  secret_key: "ultrasecretkey"  # change this!
  limiter: true  # can be disabled for a private instance
  image_proxy: true
  port: 8080
  bind_address: "0.0.0.0"

ui:
  static_use_hash: true

search:
  safe_search: 0
  autocomplete: ""
  default_lang: ""
  formats:
    - html
    - json # json is required
  # remove format to deny access, use lower case.
  # formats: [html, csv, json, rss]
redis:
  # URL to connect redis database. Is overwritten by ${SEARXNG_REDIS_URL}.
  # https://docs.searxng.org/admin/settings/settings_redis.html#settings-redis
  url: redis://redis:6379/0

The port in the settings.yml file for SearXNG should match that of the port number in your docker-compose.yml file for SearXNG.

Step 9: Update uwsgi.ini File

  1. Ensure your searxng-docker/searxng/uwsgi.ini file matches the following:
searxng-docker/searxng/uwsgi.ini
[uwsgi]
# Who will run the code
uid = searxng
gid = searxng

# Number of workers (usually CPU count)
# default value: %k (= number of CPU core, see Dockerfile)
workers = %k

# Number of threads per worker
# default value: 4 (see Dockerfile)
threads = 4

# The right granted on the created socket
chmod-socket = 666

# Plugin to use and interpreter config
single-interpreter = true
master = true
plugin = python3
lazy-apps = true
enable-threads = 4

# Module to import
module = searx.webapp

# Virtualenv and python path
pythonpath = /usr/local/searxng/
chdir = /usr/local/searxng/searx/

# automatically set processes name to something meaningful
auto-procname = true

# Disable request logging for privacy
disable-logging = true
log-5xx = true

# Set the max size of a request (request-body excluded)
buffer-size = 8192

# No keep alive
# See https://github.com/searx/searx-docker/issues/24
add-header = Connection: close

# uwsgi serves the static files
static-map = /static=/usr/local/searxng/searx/static
# expires set to one day
static-expires = /* 86400
static-gzip-all = True
offload-threads = 4

2. Alternative Setup​

Alternatively, if you don't want to modify the default configuration, you can simply create an empty searxng-docker folder and follow the rest of the setup instructions.

Docker Compose Setup​

Add the following environment variables to your Open WebUI docker-compose.yaml file:

services:
  open-webui:
    environment:
      ENABLE_RAG_WEB_SEARCH: True
      RAG_WEB_SEARCH_ENGINE: "searxng"
      RAG_WEB_SEARCH_RESULT_COUNT: 3
      RAG_WEB_SEARCH_CONCURRENT_REQUESTS: 10
      SEARXNG_QUERY_URL: "http://searxng:8080/search?q=<query>"

Create a .env file for SearXNG:

# SearXNG
SEARXNG_HOSTNAME=localhost:8080/

Next, add the following to SearXNG's docker-compose.yaml file:

services:
  searxng:
    container_name: searxng
    image: searxng/searxng:latest
    ports:
      - "8080:8080"
    volumes:
      - ./searxng:/etc/searxng:rw
    env_file:
      - .env
    restart: unless-stopped
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - SETGID
      - SETUID
      - DAC_OVERRIDE
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "1"

Your stack is ready to be launched with:

docker compose up -d
note

On the first run, you must remove cap_drop: - ALL from the docker-compose.yaml file for the searxng service to successfully create /etc/searxng/uwsgi.ini. This is necessary because the cap_drop: - ALL directive removes all capabilities, including those required for the creation of the uwsgi.ini file. After the first run, you should re-add cap_drop: - ALL to the docker-compose.yaml file for security reasons.

Alternatively, you can run SearXNG directly using docker run:

docker run --name searxng --env-file .env -v ./searxng:/etc/searxng:rw -p 8080:8080 --restart unless-stopped --cap-drop ALL --cap-add CHOWN --cap-add SETGID --cap-add SETUID --cap-add DAC_OVERRIDE --log-driver json-file --log-opt max-size=1m,max-file=1 searxng/searxng:latest

3. Confirm Connectivity​

Confirm connectivity to SearXNG from your Open WebUI container instance in your command line interface:

docker exec -it open-webui curl http://host.docker.internal:8080/search?q=this+is+a+test+query&format=json

4. GUI Configuration​

  1. Navigate to: Admin Panel -> Settings -> Web Search
  2. Toggle Enable Web Search
  3. Set Web Search Engine from dropdown menu to searxng
  4. Set Searxng Query URL to one of the following examples:
  • http://searxng:8080/search?q=<query> (using the container name and exposed port, suitable for Docker-based setups)
  • http://host.docker.internal:8080/search?q=<query> (using the host.docker.internal DNS name and the host port, suitable for Docker-based setups)
  • http://<searxng.local>/search?q=<query> (using a local domain name, suitable for local network access)
  • https://<search.domain.com>/search?q=<query> (using a custom domain name for a self-hosted SearXNG instance, suitable for public or private access)

Do note the /search?q=<query> part is mandatory. 5. Adjust the Search Result Count and Concurrent Requests values accordingly 6. Save changes
