how create meta search "dogpile" style

I found my site listed in "custom" searches performed by meta-search-engine, here is a sample: http://* www.site-city.com */collectibles/web-search/category/art-gallery-art-collectible.html where results are being targeted, in this case they used collectibles keywords.

The sample site uses a fatbomb search engine, not available a this time.

In this case this site uses art keywords:
http://* www.artpimpgallery.com */index.php?q=Claude+Monet+Famous+Paintings

I'm looking for a script similar, to crawl some major directories an save the results a cache's system or mysql table.

Any ideas???
