Yes, that's how I added it, in settings.yml, I added

  - name: ceek
    engine: ceek
    shortcut: ceek
    categories: [general]
    disabled: true

And I wrote ceek.py in searx/engines,

# SPDX-License-Identifier: AGPL-3.0-or-later
"""Ceek.jp search engine for searxng"""

from urllib.parse import urlencode
from lxml import html
import requests
from searx.utils import extract_text

# Metadata
about = {
    "website": "https://news.ceek.jp/",
    "wikidata_id": None,  
    "use_official_api": False,
    "require_api_key": False,
    "results": "HTML",
    "language": "ja", 
}
......

Of course, I changed all of this in the container. However, SearXNG did not change after I modified and restarted the container. But the code in the container has changed. I am wondering if the problem is caused by the application process running in the container not actively reloading, what should I do?

Have you actually mounted the file via a docker volume? If you only add the file inside the container and restart the container, the file will be gone again...

Apart from that this should be moved to discussions, it's not per se a SearXNG issue.

@YinSonglin1997 please stop floating the issue tracker and discussions with the same topic again and again .. we will delete duplicates silently!

I can only repeat what I have said hundred times Contact:

We have an active community .. questions, issues and more can be discussed there before opening a ticket to the core development of SearXNG. --> #searxng:matrix.org.
