Hi all, I know that currently most languages aren't available in Joomla 4 beta, so maybe this issue won't be bothered until Joomla 4 RC. I had a test site update from Joomla 3 -> 4, so my site has English and Chinese.

Steps to reproduce the issue

Multilanguage Joomla 4 Beta 8 site
Create content for English and other non-english Language (In my case, Chinese)
Use finder to search for content
When on English version of site, can search for non-english queries like (ex: 周佳宥), but when you filter switch to Chinese, the query can only find english terms, and cannot find any queries that aren't in Chinese (English queries work) . Screenshot attached below

Expected result

Can search for any terms whether english or not, or on which language filter the site is currently activated on.

Actual result

As mentioned, you cannot search for non-english queries when on the "non-english" language filter, but can when on the english version of site.

System information (as much as possible)

Additional comments

I'll be happy to help tackle this issue, but will need some guidance on where to start.

Both using the exact same query: 周佳宥 (chou chia yu)
