Is there an on-line search engine that allows you to search across
multiple newspapers?

I believe that most newspapers with websites have a classified ad
search option. Is there an on-line search engine that allows you
search across multiple newspapers?

For example; if I'd like to buy a dishwasher, is there a way that I
can search and find a 'classifed diswasher ad' in any of the major
newspapers in the United States or Canada, without having to search
directly on each individual newspapers websites.

Thanks.
