I am using Apache Nutch v1.10 and SOLR v.5.2.1 to index and search a medical website and am trying to find out why every stemmer I've tried on certain nouns in medical terminology ending in 'y' merely replaces the ending 'y' with an 'I'. As example, the term 'osteopathy' stemmed with the Porter Stemmer Filter stems to 'osteopathi', which will match 'osteopath' and 'osteopathic', but will not match the original term 'osteopathy' itself. I've seen this with quite a few medical and science nouns ending in 'y' (though, oddly enough, the word 'terminology' itself stems to 'terminolog' just as I would expect it to) and am wondering whether there is a different stemmer I should be using, or if I am just using this one incorrectly. I am currently applying the PorterStemFilterFactory to a field of type 'text' in both the indexing and querying analyzers. Any comments, suggestions or explanations would be much appreciated.
