Does that mean it searches private info? Or does it mean that nobody uses it? Maybe it means that the searches are anonymized?

andrewfhart• 13 years ago

The last. It basically acts as a proxy: You type in your query, and IxQuick (aka startpage.com) queries Google on your behalf, thereby shielding you from the associated analytics and tracking. It also claims to not store the IP address associated with an individual query.

From their site:

-You have a right to privacy.

-Your search data should never fall into the wrong hands.

-The only real solution is quickly deleting your data or not storing them to begin with.

-Since January 2009 we do not record our users' IP addresses anymore.

-Your personal data are not shared with any third party.

-We are the first and only search engine to do so.

-Since then we have added many other features that protect your privacy.

-Our initiative is receiving an overwhelmingly positive response!

I usually use DuckDuckGo.com, because they have a neat toolbar and I want to support their cause, but everytime I don't get the results I want through DDG (which happens rarely) I just type !sp + searchterm into my search bar and it searches via startpage.com, which uses googles search results without my IP address or searches being recorded, no identifying or tracking cookies are used and SSL encryption is set by default.

Startpage.com was launched in 2009 by ixquick to create the same service via a URL that is both easier to remember and spell.

Wrong, it is not same service.

Scroogle was a similar and quite popular site, but Google blocked it.

I wonder what it takes to host a full search engine for the Internet now, if an organization wanted genuinely private search. Presumably you can buy crawls from somewhere, but does anyone sell a self-hostable general web search engine?

There are GPL'ed peer to peer search engines like YaCy.

Unfortunately it's practically useless. But try it out anyway: http://search.yacy.net/

That I'm aware of there are only three places to get actual search index results in the US, Google, Bing (via Yahoo BOSS), and of course Blekko. You can also get index results from both Yandex (Russian) and Baidu (Chinese) but both serve them out of data centers in either Amsterdam or Asia respectively so latency is a bit longer.

With modern hardware (especially 3TB drives) you can crawl a significant chunk of the Internet with as few as a hundred machines but in practice you will want closer to 300. Of course crawling is but one (relatively small) step in the series of steps needed to create an index, next up is page extraction, then term extraction, then semantic analysis followed by meta-data decoration (is it likely porn or maybe malware or junk, did it change since the last time you looked at it, what is a good snippet, etc etc) Then you process link information and perhaps click stream data and create your ranking model, which then lets you build an index. At which point you need another bunch of machines which can efficiently take a query string and put together a set of documents that might be a good fit (straightforward for 1 term, harder for 2 terms, exponentially worse for 3, 4, 5, 6 or more terms).

Depending on latency requirements and load you make that part of the system in another few hundred machines.

Search results though also have an inverse power law associated with them, the most popular consumer results fit in a .5 billion URL index, the 95th percentile in a 3 - 5 billion URL index, the 99th percentile is probably closer to 45 - 50 billion URL index. At the 95th percentile you're up to a few thousand machines to hold it all.

It isn't really possible to build on a generic VPS yet (like ECS on steroids) without having latency being ridiculous. It would also be expensive, the last time I did the calculation for the memory/compute/storage resources (pretending the latency could be fixed) it was about $2.5M/month in resource fees for a 1/2 billion page index and crawl. Since that time both Amazon and Google have lowered some prices so it may be more affordable now.

Putting it in a data center is much cheaper than that but not quite cheap enough to just let it sit around without monetizing it somewhat.

I'm a bit surprised that someone hasn't put something together, there are bits and pieces out there. But even self-hosted you're looking at least a few hundred thousand $ a month to keep it up and since Yahoo will sell you access to their search API for a couple of bucks per thousand queries it's probably not worth it for most people to try and run their own.

A few years ago, before JumpTap pivoted to be a mobile ad network, they built a search engine using off-the-shelf parts on a hosting service. Some of the founding team members were from Lycos, and they had a pretty good idea of how to do this.

It was not run at general-purpose production scale, but they did show they could produce credible search results at a relatively small scale.

There are several open source spiders out there. As Web search portals increasingly aim at the broad middle, I sometimes wonder if doing your own domain-specific spidering might find interesting things.

I guess it would make more sense to let an organization specify sets of interest. Optionally fail-through to external public search engines if necessary.

e.g. if I were an intel agency, I'd crawl all the jihadi sites and build a special translation/search tool for those (I'm sure they've done this). No need to crawl the rest of the pornosphere, so it could be done on one box. A commercial company could search all their industry sites locally, and then fail-through for general stuff.

I guess my main question is "how many machines are needed to do 1-3 term search on a 0.005-0.5 billion URL index" for one user with decent latency, and then how many simultaneous users could be served from that, after the index is delivered". The idea being that organizations will trust the security guarantees of a machine they own, so you could build a search service in a way that the crawl/etc. is done by one set of shared machines, bulk data streamed to everyone inside the datacenter, certain data (up to the entirety) retained by each end-user organization's query cluster, and then queries done by that cluster locally to keep search terms secret.

I assume the actual query part could fit on single machines -- you would sort of want to keep cached pages for a lot of the things you'd want to keep searches secret for, but disk is cheap.

I've noticed while using this that the results are often very different to google's (and generally inferior).

Sometimes I find myself switching back to "regular" google, but not as often as when I used duck duck go.

One thing that really bugs me is that I can't do currency conversions or calculations in this one.

stinos• 13 years ago

this, plus the lack of completion in the search box.

http://startpage.com serves also Google results.
