OK. I already had that word length option set to 1. That would be brilliant. I have recently removed taxonomies from results because they were so unfocused and the products came too far down, but my business partner uses them a lot so is keen for them to be reinstated.
I’ve set up a page with both available in case that helps. To be honest, there is some quite odd behaviour in the filters.
