I have just contacted support about a problem with the search in all languages other than the main language. I needed to try something, but unfortunately it did not work. I needed to contact support again if it did not fix the issue.
Languages: English (English )German (Deutsch )French (Français )
Timezone: Europe/Zagreb (GMT+01:00)
Can you please try the following:
On this sandbox: hidden link
1. Install "Filter Everything"
2. Create a product including all relevant details and an SKU.
3. Translate the product
4. Configure a filter
5. Test the search by applying the filter on the front end to check if it recognizes the translated product.
Let me know where the search or filter setup shows errors or doesn't work as it should.
I have found a workaround by using the search field from my theme in combination with the filters, and that seems to work fine. So no further investigation is necessary. Thank you so much for all the support and help.
