Characters' Names

A few years ago, there was an option in the movie title advanced Search, that we can write the name of the movie characters and see the list of the movies in which the actor/actress has the same character's name and also when checking a movie title and click on the name of a character (which written opposite the name of an actor/actress), again we can see the list of the movies that have the same character's name on them

I have a question why has IMDB deleted this option?

Is it possible to activate it the same before?
