I am using Google Custom Search for my site. I want Google to provide at most 2 searches from a site. I am not sure whether it is possible or not, but it seems there is no such option on Google CSE.
For example, my CSE has 10 listed sites. What I want is that whenever a user makes a search then search results should show at most two links from a site. In general CSE is returning multiple results from one site only and these come on page 1. If it is at most 2 from a site then the user has a better chance to have links from other sites too.
