Laravel forget cache - laravel

Question

Laravel 8.0 CACHE_DRIVER=file.
Stored in cache 'posts' and 'post_detail'.
I'm using full url for save in cache unique page of pagination posts.
public function __contructor()
{
$this->full_url = request()->fullUrl();
}
// ALL POSTS WITH PAGINATION
public function posts()
{
if (Cache::has("posts_".$this->full_url)) {
$posts = Cache::get("posts_".$this->full_url);
} else {
$posts = Cache::rememberForever($this->full_url, function() {
return Post::paginate(15);
});
}
}
// DETAIL POST
public function post_detail($slug)
{
if (Cache::has("post_detail_".$this->full_url)) {
$post_detail = Cache::get("post_detail_".$this->full_url);
} else {
$post_detail = Cache::rememberForever("post_detail_".$this->full_url, function() {
return Post::where('slug', $slug)->first();
});
}
}
I can forget cache only for 'post_detail' but I have no idea how to remove the cache for all posts that include the key 'posts_'
// UPDATE POST
public function update()
{
...
$post->update();
$full_url = $request->getSchemeAndHttpHost()."/".$post->post_categories->category_slug . "/" .$post->slug);
Cache::forget("post_detail_".$full_url.""); // OK
Cache::forget("posts_*"); // forget al posts contains 'posts_' key.
}
thanks
