Filtering and showing documents

I’ve got a website where i use my ditto in.

this website shows blog pages posted on dates.
on the home page will be shown the 3 latests posts and when you click on one post that post will open on a new page.

on this new page you will see the complete post you just clicked and then you will have to see the 3 articles that come after that post.
so if the post i am currently on is published on 21 may i want to see the posts that are posted from example 20 may , 19 may, 18 may,

currently he will show only the latest 3 published ones. so like 21 may 22 may 23 may.
can anyone help me with this issue and show me how i can make a nice archive on my website

On your new page (i.e. containing just-clicked full article) you should once again call ditto like this:

It means: get three articles sorted by creation date in descending order but exclude those whose creation dates are newer or equal to creation date of the article just-being-processed (its date is represented by a placeholder [+createdon+])
