Mark: Just a sanity check, was the indexing porter stemmer defined when you indexed your _first_ document? The admin/analysis page will tell you what the term is stemmed to at both query and index time.
I'm puzzled by this statement: bq: As example, the term 'osteopathy' stemmed with the Porter Stemmer Filter stems to 'osteopathi', which will match 'osteopath' and 'osteopathic' Why do you think this will match? the stemmer wouldn't stem the 'osteopath' to the term in then index, namely 'osteopathi' and thus wouldn't match. Or at least shouldn't.... So I'm probably missing something here... Best, Erick On Thu, May 19, 2016 at 12:31 PM, Markus Jelsma <markus.jel...@openindex.io> wrote: > Hello - try the KStem filter.
