Many to one relation post

Is there a way to have all the posts with a custom taxonomy display on a single post?

What I mean is:
I have a bunch of posts with a custom taxonomy (genre). When I apply a search, it returns those posts in an array.

What I want to do with the search is when someone searches a specific genre, instead of a full list of posts, I want to have just one post. This post, when someone clicks into; reveals all of the posts in (genre).

I know that I can just put some copy & links into a page, and search for pages, but I would have to put content in two different areas every time I update data. I would like to avoid having to do that.

I know very little PHP, so if there is a plugin that lets me accomplish this, that would be awesome! All help would be appreciated.

Thanks!
