Hi to all,
I'm developing my clustering engine but I have a lot of difficulties regarding search results. Many search engines don't permit parsing of their HTML (..and I think that it is not a good method because they often change their html) and some API has serious limit.

E.g. I'm using Yahoo API for my prototype but they have some performance limit: query "jaguar", about 4 secs in order to retrieve search results...too much.

Do you know some professional search results feed in order to give a better showcase of my WebClust Clustering Engine?

Thanks,
V.B.
