Thanks for the input! We've discussed using synonyms to help here. We have product managers who are supposed to add keywords on to skus also which our indexer will automatically consume. Getting them to do that is a different matter! haha

This is very domain dependent, as you've discovered. I doubt there's even such a thing as the way everyone doing a 'retail product title search' would want it, it's going to vary. You could use the synonym feature to make your own stemming dictionary, tell it to stem "seating" to "seat". Of course, that's also very "expensive" in terms of your time, to create your own custom dictionary. But you're going to have to live with one of the compromises, software cant' do magic! For particular titles, you could also, in your own metadata control, add "alternate titles" that you want it to match on, before it even gets indexed.

We wanted a less aggressive stemmer, but I would expect the term seating to stem. I have found several other words which end in ing and do not get stemmed. Amongst our product lines are four million books with all kinds of crazy titles, like the following oddity! Here counseling stems and unknowing doesn't: > > 1.
