I just started an aggregator devoted to blogs about the Israeli-Palestinian conflict. I'm using Wordpress and the FeedWordpress plugin to populate the site.

But there are a number of sites which cover a variety of topics, only one of which is the Israel-Palestine conflict. These sites don't necessarily have specific categories dedicated to the Israel-Palestine conflict or rss feeds for those categories. As of now, I can't feature any material fr. such sites.

But I was thinking that if there was a plugin or other technology which would allow me to list those blogs & use a keyword search in order to find blog posts about the Israel-Palestine conflict, then I could feature material from such blogs.

Would anyone have any idea if such a thing might exist?
