Hi there,
Thanks for this useful piece of information! What I'm wondering is how
do stemming on queries as well. My first try was:
query = Ferret::QueryParser.new(:analyzer =>
Ferret::Analysis::StemmingAnalyzer.new).parse(query_string)
index.search_each(query) { |doc, score| ... }
But this does not work the way I would expect it to work, i.e., it seems
to deliver empty results independent of the input.
Does anybody have an idea what I'm doing wrong?
Cheers,
Albert
