Building a Bigger Search Engine 278

skreuzer writes "Wired is running a story about a distributed web crawler called Grub. People who choose to download and run the client will assist in building the Web's largest, most accurate database of URLs. This database will be used to improve existing search engines' results by increasing the frequency at which sites are crawled and indexed. Conceivably, Grub's distributed network could enable state information to be gathered on every document on the Internet, each and every day."

    I started to use grub, but then questions started cropping up. First we are using this to further a commercial organization. This is not research such as SETI or Folding At Home; this is doing the dirty work of a large commercial search engine. There is not even any potential reward such as with distributed.net.

    Also the grub engine crawls everything, including adult content and other questionable content. They have a setting to turn it off, but it does not block it. With the current questioning of international law relating to accessing illegal websites this could have major consequences for the average user.

    So for the time being I have stopped using the grub client until some serious questions are answered. It's an interesting concept and if it was being used in more of an academic setting it could be interesting. However I believe that search engines like Google are doing pretty good themselves.

      Actually, if I had a gun to my head, I'd choose to run Grub, because the client is open-source. I used to run SETI@home, but then the news came out that they'd been sitting on a potential root vulnerability for a long time. That really brought home to me the risks of running someone else's closed-source app on my box.
    • Yeah, god forbid you help a commercial organization, especially when the results could stand to benefit you.

      God knows that Google, by virtue of being a commercial entity, has absolutely nothing to offer you.

    LookSmart hopes to tap the altruistic nature of many Internet users.

    That unfortunately seems like a naively optimistic hope. While the
    vast majority of people may be altruistic, it only takes a few
    unscrupulous individuals to completely undermine a fair result.

    It's interesting that this idea is an extension to Google's model in
    many ways. Essentially Google is able to index so much of the
    interent by having 50,000+ servers. I don't think that's what makes
    Google such a useful search tool, rather I think it's accuracy and
    relevancy. If my search results started getting poluted with bogus
    hits, I would stop using it almost immediately.

    Unfortunately, by letting people run the client on their machine and
    having it send the results back to the server, I think spoofed
    results are inevitable. I don't think it will be possible to
    safeguard the results either, it will be interesting to see how well
    this project survives *when* people start spoofing results. It's
    been a problem for SETI@home, and it's something that undermined some
    peoples faith in the project as a whole. If the spoofed results are
    more widespread and have a larger impact as they would in a system
    like this, it may ultimately prove fatal to the project.

    One factor that has been asbolutely critical to Google's success has
    been their ability to remain resistant to spoofing attempts. It's
    still a question mark how well grub will perform in that context.

    So Grub goes out, uses bandwidth, and then returns some results to the home base. It's really distributed bandwidth more than distributed computation.

    I bet one of the big successes in Folding and distributed.net is that many people run the clients on work boxes, knowing that there's little actual overhead incurred to their work. How different that is for a URL sucker.

    until someone figures out a way to compromize their local client's results and "escalate" their fave URLS.

    It still sounds like a really cool idea though.

    • Grub's clients don'tcome up with a ranking for each website they crawl; rather, they check to see if this website has changed since the last time it was crawled. For any website that has changed, the client notifies the server. The search engine asks the server which sites in its index need to be updated, and the server gleefully replies.

      Clients artificially increasing their ranking isn't an issue, since the client has nothing to do with a site's ranking.

    It is too easy to send currupted information into the database. They have *no choice* but to trust the clients. Sure they could run spot checks on the results, but they would be very partial and it would be easy enough to fake responses for those as well.

    So the more popular it gets, the more incentive people will have to promote their sites by feeding it fake index information. If this magically got to be very popular, within weeks search results would become meaningelss and it would drop back into obscurity. The more likely result would be that it will never become popular in the first place.

    Besides, who wants to donate his CPU and bandwidth resources for a commercial company, anyway?

  • Normally, most search engine's spidering methods are designed to be pretty nice to servers - such as only requesting pages once every 30 seconds or so.

    However, I've seen times when the methods of some of the search engine spiders were foiled by such simple things as having a large number of virtual hosts on a machine. Combine that with a number of front-end machines all connected to the same database server, and things can get really nasty.

    In one particularly bad incident, several fairly big-nam
  • 1. Design a search engine
    2. Let everyone else fill it
    3. Profit

    The second step is finally found!!! YAY
  • I'm sure grub will indeed build a larger database than most other search engines, since grub (or grub-client, or whatever it's calling itself) has never, not even once bothered to look at a robots.txt file on any web site I've ever administered. This is what webmasters call a misbehaved robot, and it is not something to be looked at with respect.

  • The common point made by these "distributed" software authors is that there are "wasted" CPU cycles in your computer that you could donate to a project for free.
    However, that is not true at all! CPU cycles are not wasted. When the CPU has nothing to do, it sleeps. At least in a modern operating system (i.e. about everything after Windows 95).

    By "donating your wasted CPU cycles" you will actually increase the power consumption of your computer. This will be very noticable in a laptop, but when you watch
