Solr Facetting - Showing First 10 results and Other

Question

I am implementing a solution in Solr where I have a lot of values in my facet.

As opposed to displaying a long list of values(facets) down the side of my page I want to display the top 10. And also have one for other.

For instance I would be faceting on Nationality.

So, I do not want to have a list of every nationality, Nor do I want a "see all" button.

What I require is the top 10 nationalitys and then "Other".

When a user clicks on other, it facets on this?

This is quite easy in Solr.. All you need to do is add a

&facet.limit=10

e.g.

http://solrserver:8080/solr/select&version=2.2&q=solr&start=0&rows=0&indent=on&facet=on&facet.field= nationality&facet.limit=10

to your request and you should be able to limit the results.
