Is there any way, using Diigo, to search the entire site of bookmarked pages i.e. not just the saved pages, but the entire site that they come from?

Thanks for the suggestions. I use the Google Toolbar to search the current site. What would be nice is to be able to search a bunch of related sites at the same time. You can do through various web sites. You have to set up a group of sites that you want to search i.e. create your own search enging e.g. http://www.google.com/cse/. I thought it would be a lot more convenient if you could somehow do it through Diigo. Oh well.
