It's only showing results from the paid search engines because they have gone from offering a nice meta search engine to paid results via their partnerships with the $$ search engines. Kind of like a prostitute which is what they are now. I really used to like ixquick, now it's no better then one of those fake "search engines" you see all the time. = junk.
Seems strange as they still have the other engines at the top of their page but they don't retrieve from them. If that's what they have done they won't last much longer, a shame really, I used to use them quite a bit, now it's useless.
