[Koha] Stemming and zebra

[Francois Charbonnier]

Hello,

I have tested the QueryStemming system preference on Koha 3.14 (my local 
installation) and I'm wondering, does zebra just right truncate the 
words or is there an algorithm to find the stems?

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?

Thanks!
