Hi Francois
Writing from a tablet so I will be brief. If you’re not using queryparser, there is a Perl module that does the stemming I believe. Lingua::Snowball or something like that. It would be easy to add to the queryparser too but haven’t gotten to it yet. Oh… now that I think about it… I think we mangle keywords before stemming them. I can’t remember why but there was some reason for it. Sorry this message is so incoherent. Will investigate and type a better response when I have a proper keyboard and not just thumbs on a small screen.

I use ICU and I have enabled "QueryWeightFields". I don't have automatic truncation or fuzzy search on. I use these words for my tests: * ski, skiing, skills * fish, fished, fishing, fisher, fishxsdfe Each time, with QueryStemming on, skills and fishxsdfe come out in the search results. Is it what I should expect? "Skills", maybe but "fishxsdfe"? Do you know how it works? or have a good example that would help me to understand?
