isn't this.find in post hook unnecessary? because the query has already run on the db, if we really want to filter, shouldn't we use filter method on docs itself?

I came in comments section to ask the same question. I think he forgot to remove it since he copy-pasted the pre-hook. I googled around and came to know modifying the query in a post hook won't affect the actual database query that was executed.
So it's just a mistake.
