Idea for better seach engine

Hi. Parent's guide has "categories" (can't find better word in my brain) Sex&Nudity, Violence&Gore, Profanity etc. So search would be much better if we would be able to select level (e. g. none, low, mild, moderate, severe) of each category.

But first you should "repair" your search engine. In search I selected TV series, genre: action, keywords: f-word, profanity. But many action series with lots of profanity are not displayed in search result.
