Question: How good is Gigablast? Would they make a good choice to license for a search engine project?
I've played with Nutch, but for my application, I'm more concerned with the search database quality. I want some good results and to outsource the spider part.
Bad idea. Any server/search engine running Apache will ultimately be a lot slower than Google. Try Lighttpd
Huh? Lighttpd is a web server, not a search engine. Regardless, Nutch is the back end - you can use whatever web server you wish to use as the "front end". Crawl the web - put results in database - use Nutch to pull results or write your own middleware.
Maybe I need to clarify my question a little bit. I am wanting to start a search engine portal. I do not want to run my own spider. I just want to focus on the usability and GUI so I can do some new stuff to make searching more fun. I also want to try some new ways to tie in ads and social media. Is Gigablast's engine and database a good one to license?
