The configuration seems to be correct – the issue is, that the “Organisation” page is in english language only. When I switch to the english language, and search for the post, it shows up correctly.
If you add the french translation to it, it should start showing up as well.
However, I wonder if I have configured the module correctly because the page does exist in French. I just have the impression that it does not appear in the results because there are many more FR pages than EN.
No, I tried a few options, and it seems the date filter is at fault there, it is set incorrectly. When I set to earlier date, it works: https://i.imgur.com/GqBQs1t.png
The post is dated to 18th of december 2017, while the filter removes everything before 1st of january 2018 – including the “organisation” post. I just noticed that. If you set the date on the filter to an earlier date or make it empty, it will work.
