I saw that on the site link has a field to do the search by get the url get does not follow a pattern, I think it is encrypted.

Example of the url with the search.

Search for: 1877 url: link

Search for: 1876 url: link

Can you make this query by contest through the url?

It seems that even informing the modified url it brings the most recent result.
