Heya @KarolyNegyesi , sorry to hear about the trouble here.
Is there another search engine that does surface the results that you expect? I ask because - for the time being* - Kagi is not a discrete, independent search index, rather we aggregate all of the results we can get from all other major search engines in "one shot", asking for as many results as their APIs will give us in a single call, then merging them all together and filtering out any easily identifiable "cruft".
With very few exceptions for corner cases, Kagi does not manipulate your search terms, they are passed upstream as you wrote them.
Which is to say, that if you can't find it in any other engine, there's unlikely anything we can do directly at the moment to improve this. But if you can, then there is a chance that we are wrongly filtering out the result for some reason. I tried on Google and Bing real quick, and wasn't able to see it there either, but let me know as things like your assumed location can influence results, among other implicit factors.
* - We do have a couple of our own "mini indexes", but they are very small and focused on things like blogs and other evergreen webpages (e.g. https://kagi.com/smallweb). We are working on building our own independent large-scale index with a dedicated team allocated to it, but this will take some time to fully materialize in production results.
