Mflix controller questions

    [HttpGet("api/v1/movies/")]
    [HttpGet("api/v1/movies/search")]
    [HttpGet("api/v1/movies/getmovies")]

Like every operation of the objects like movie, user, and comments are all have this type of lines in the controller files.

What are all these, aren’t these the input for the controllers? And what are these component in the mflix controller correspond to?

I am doing a similar project and this question is my biggest concern.
