array issues

Hey all, When I do: @posts = Post.find(:all)[0,5] it gives me the first 5 posts

But when I do: @posts = Post.find(:all)[10,20] it gives me something like 20 posts or more, shouldn’t this give me only 10 post from 10 to 20?

what am I doing wrong?

thanx in advance

No, on an array it works like this..

array[offset, length]

So Post.find(:all)[10,20] will give you 20 posts starting at number 10.
