The stemming uses Lingua::Stem::Snowball to perform compute stemmed form
of search terms. Then it is used in _build_weighted_query to add a query
with left truncation.

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!
