combine (like + in) inside where query

I have a posts table (Post model), I want to search for a string like this (Laravel query builder), and I want to search to run like the following:

1- explode search string to create array

$keys = ['Laravel', 'query', 'builder'];

2- search if any item in the array is found in post title or post body

$posts = Post::where('title', 'in', $keys)->orWhere('body', 'in', $keys)->get();

$posts return an empty array, I don't know if the previous eloquent statement has any thing wrong
