If you can scrape findthecompany database ? I have done it successfully !!
If Google wanted to give back something to the community, it would offer cheap automated searches (current prices are absurd). Another thing - more depth after the first 1000 results. Sometimes you want to know the next result. We shouldn't need to do all these stupid things to batch query a search engine, it should be open. That makes it all the more important to invent an open-source, federated search engine, so we can query to our heart's content (and have privacy).
duckduckgo is good but not there yet.
Would you be interested to work on a search engine ? Some projects are bitfunnel and so forth.
As for 'federated search engine' - it's not 'federated' per se but check out Gigablast search engine. Open source (source on GitHub) and a TOTALLY AWESOME piece of software written by one guy. You can do good searches at the Gigablast site[1], or set up your own search engine. Gigablast also offers an API (I may be wrong but I think DuckDuckGo uses that API for some tasks).
