Overview

I tried Wagtail, so here are my notes on issues I encountered.

I basically followed the tutorial below:

Your first Wagtail site — Wagtail Documentation 5.0.1 documentation
docs.wagtail.org

Search Feature

When I added a page with the Japanese title "My First Article," the following search did not return any results.

http://localhost:8000/admin/pages/search/?q=はじめて

On the other hand, the following search did return results. It appeared that partial matching for Japanese is not supported by default.

http://localhost:8000/admin/pages/search/?q=はじめての記事

Wagtail API

Information about the API is available here:

Wagtail API — Wagtail Documentation 5.0.1 documentation
docs.wagtail.org

By also adding rest_framework following the site above, I was able to get results as shown below.

However, the hostname in the results was showing as localhost even though the app was running on localhost:8000.

This issue was resolved by modifying it through the admin panel, following this article:

Edit approved email points to localhost
After approving a change in the Wagtail admin, the editor receives an email letting them know the page is published. The problem is the link to the page doesn't use the site domain, but localhost: ...
Stack Overflow

Specifically, I changed the port number on the /admin/sites/ page.

?search Parameter

As with the search feature above, it appeared that exact matching was required for Japanese.

http://localhost:8000/api/v2/pages/?search=はじめての記事

Elasticsearch

I tried integrating with Elasticsearch.

Backends — Wagtail Documentation 5.0.1 documentation
docs.wagtail.org

This time I tried AWS OpenSearch, but the following error occurred.

elasticsearch.exceptions.UnsupportedProductError: The client noticed that the server is not Elasticsearch and we do not support this unknown product

A similar issue was raised in the following link, but it appeared to be unsupported at the time.

Summary

This may contain some inaccuracies, but I hope it serves as a useful reference when using Wagtail.
