Building a Search Engine Using Open Technology?
cybrthng asks: "Mozdex.com is my attempt at building a search engine capable of indexing the entire web. Our goal is to provide a completely transparent system utilizing open technologies such as Nutch, Lucene and other systems to provide a search facility that is more scientific and 'protocol' vs the current propriety and almost 'faith based' search engine results and methods of getting listed. What do you look for out of a search engine? What would you look for out of this project? Should large commercial entities be the only way we find information and resources on the net? BTW, our beta index currently has about 50 million pages and we hope it shows what can be done using Open Source systems available today. We are seeking input on starting a developer & input community as well as getting concepts and ideas out and about, so we value your ideas and what you hope to see out of this project."

Is it different only because it runs on open source software? Hell google does that successfully already.
The thing I look for is a polite bot. Does it follow robots.txt fully? Does is hammer the server? Does it page modification headers?
What would you look for out of this project?
The only thing that matters is results. Is the answer that I need in the first three or four results? If you can do that, you win. If you can't, don't bother.
I'm skeptical about how realistic it is to develop an open source search engine. Wikipedia, although cool, has large gaps in content, and only a few months ago was begging for donations to survive. I'm betting that a Google sized operation would be even more resource intensive.

No, it's a game where those who focus on the value of their content lose to those who focus on the marketing of their content.
I've had this sig for three days.
You could do that by (a) putting in more keywords; (b) letting the search engine suggest topics/extra search keywords for a given search; some search engines try to do this already. As to how, latent semantic indexing looks good (it's a matrix technique used to find relationships between bits of data, such as the ones you discuss)

I'd love to be able to filter out all sites that are trying to sell something.
Searching on Google for things like reviews of mp3 players has become a nightmare these days. Any useful sites are drowned out in a noise of pricerunner/dealtime/kelkoo/shopping.yahoo/etc and other sites that are simply affiliate sites for Amazon etc.
An OSS search engine that actually indexes the entire web and is used by many people is at least a couple of orders of magnitude harder than the Mozilla project.
Writing the search code itself is not too hard (you still need a PhD in data structures and algorithms, but those can be found), the real hard part is the amount of bandwidth and CPU power that is required.
Try this:
MP3 player review -buy -dealtime -pricegrabber -kelkoo -shopping.com -amazon.com -nextag.com -bizrate.com -moreover.com -celeb -porn -free -coupon -pimprig.com
I have it set to a hotkey for all the -'s and boom relatively valid search results.
