Best practices for no search results
I always get angry when I refine my search applying filters in any website and I get the 'no results' page. Why do they show me an option that will lead me to a blank page?
I am trying to combine 2 filters. Language and category for an educational website. If I choose english, I would like the system to show me only the categories in english I may choose from. And if If i choose first a category, I would like to have only valid options for the language, do not let me choose a language that has nothing in there!
