like this?

however i don't thinks what i did is a proper way of doing it, i used same search as in documentation page by making some changes in templatetags/docs.py

def search_form(context):
    request = context["request"]
    version = context["version"] if "version" in context else context["DJANGO_VERSION"]
    lang = context["lang"] if "lang" in context else context["LANGUAGE_CODE"]
    release = DocumentRelease.objects.get_by_version_and_lang(
        version,
        lang,
    )
    return {
        "form": DocSearchForm(request.GET, release=release),
        "version": version,
        "lang": lang,
    }

and in 404.html

{% extends 'base_error.html' %}
{% load docs %}

{% block title %}Page not found{% endblock %}
{% block header-classes %}
container--flex container--flex--wrap--mobile
{% endblock %}
{% block header %}
  <h1>404</h1>

  {% search_form %}

{% endblock %}

{% block content %}
<h2>Page not found</h2>

<p>Looks like you followed a bad link. If you think it's our fault, please <a href="https://code.djangoproject.com/">let us know</a>.</p>

<p>Here's a link to the <a href="{% url 'homepage' %}">homepage</a>. You know, just in case.</p>

{% endblock %}

A more proper way would be writing a handler for 404? but maybe i should ask permission for it before

Hi and thanks for offering to contribute! 🎸

The file is there: https://github.com/django/djangoproject.com/blob/main/djangoproject/templates/404.html

For reference, I found it using this command: git ls-files '**/404.html'

Hi and thanks for your time.

i was setting up the environment by using docker but faced the same error though i followed the documentation .
If I could get the solution it would be great help

Hi! I would love to contribute to this project! Is this issue still prevalent?

I realize only now that we have a fundamental UX problem that could be blocking.

I believe that the 404 template is used for all 404 errors both on the site (https://www.djangoproject.com) and in the documentation (https://docs.djangoproject.com).

The search is only present in the documentation subdomain, so whoever were to view the 404 page in the domain (https://www.djangoproject.com) would see a search that is actually from the domain (https://docs.djangoproject.com).

The solutions proposed so far therefore I do not think are mergiable.

I see two alternatives:

1. have a specific 404 template page to be shown in the domain (https://docs.djangoproject.com) with the search and leaving that of the domain (https://www.djangoproject.com)
2. implement a site-wide search as in this issue Site-wide search #1499

Cool, I will try out the first alternative.

Hi! 👋 I'd love to contribute to this issue. Based on the discussion, it seems like a separate 404 template for the documentation site would be a good approach. I'll share updates soon.

Is anyone currently working on this?

I would guess not!

Your comment prompted me to look here again, and now I see that there's an open PR with recent activity. #1923

Seems like it's just waiting for review. 👍
