Do u mean to list all the search results together instead of the filter.Thats not difficult.All you need to do is search the different entities one by one and then append the results.Do have a look at the search mod.

I didnt understand your first question.Please clarify.

Like anirupdutta said, its not a difficult job. There are many rate entity  plugin available here. You just need to use one of them and add the rate view to the entity listing view.

Hi

Thanks for your replies.  Do you know how I could access the search results entity so I can embed the fivestar code into it? 

Thanks
