Using the actual Wikipedia search involves an extra step where I google for "wikipedia". I can skip this step if I just google for the thing I want directly on Google.

I think that says more about how good Google is than how bad Wikipedia is (although I do agree that the Wikipedia results page needs work).

JohnsonB• 15 years ago

Most people use Google search for Wikipedia because it's simply easier, instead of navigating to Wikipedia and then typing in your search, just type in your search where you usually do. Nothing you redesign on wikipedia.org will ever change this fact, people's shortest point of access to a specific Wikipedia article will still be their browser search bar or homepage set to Google/etc.

If Wikipedia's search can be improved it's simply from an accuracy standpoint. I would guess that Google employs more sophisticated spelling correction, stemming, auto completion, etc. Developing all these features to Google's level is very expensive and in that case it might make a lot of sense to just use Google's technology for the Wikipedia search.

I type "en<tab>" and then enter my query (in Chrome, at least). Doesn't get much better than that.

However, if I didn't have that feature, I'd probably use Google anyway. Tweaking the CSS won't change that. They'd really have to make Wikipedia's search kick ass in some other way.

Does Chrome's search give you realtime term completion? If you start typing in the search box on Wikipedia, it will give you suggestions that are the titles of articles. It's a substantial usability improvement over just typing something, since it gives you the opportunity to skip directly to a page more often, rather than going through the vigorously mediocre search results page.

DieBuche2• 15 years ago

Of course it does.

ramidarigaz2• 15 years ago

To echo DeBuche, yes, it does.

The thing is, Wikipedia's search is pretty straightforward: type keyword, arrive on article page.

Anything you'd add to that would detract from the search experience, not improve it. Seems to me the reason why people use Google to search wikipedia is because it saves them a step, not because wikipedia's search is inherently broken.

In any case I'd like to take part in the contest, but so far I can't really think of a way to improve wikipedia's search…

pjscott3• 15 years ago

The problem is when your search doesn't bring you immediately to the right article -- if it's not a simple search term like "Bermuda Triangle" -- and you end up looking at a page of results like this:

http://en.wikipedia.org/w/index.php?search=wireless+router+f...

Those are actually pretty good results, but their presentation is lacking. The snippets of article text are too short to give a proper idea of what the article is about and how it relates to the query terms. The formatting is straightforward but not particularly good or bad. The article metadata in green is nigh-useless to the vast majority of people; do you want text like "11 KB (1,170 words) - 12:19, 10 July 2011" cluttering up each search result? The section headings, like "Content Pages" and "Multimedia" are simple links, and it's not visually obvious under what circumstances you might want to click them, or what will happen if you do.

That's just off the top of my head, and I'm not a designer; just someone who cares about usability. I imagine a good designer could make something quite a lot nicer than Wikipedia's default search pages.

Here's a better search, I've mapped it as a keyword w http://google.com/search?q=site:en.wikipedia.org/wiki/%20%s&...

thus you can type 'w india china war' and it returns: Sino-Indian_War

> thus you can type 'w india china war' and it returns: Sino-Indian_War

That's the first result for Wikipedia's internal search, too: http://en.wikipedia.org/w/index.php?title=Special:Search&...

The reason Wikipedia's search is broken isn't (only) because it doesn't take advantage of the interesting data representations you can use; it's also just a really shitty search algo. It doesn't make any guesses, it doesn't look at related terms, and it often won't bring up the relevant article unless you specifically type that article's name.

There's a huge opportunity to beautifully represent information on Wikipedia and make search easy, intuitive, and informative, but it all rests upon having a search algo that isn't utter crap. The WMF will have to fix that before any of this will have any practical benefit.

As an ironic aside, it seems that Wikipedia isn't OSS. I can find the repo for MediaWiki, but Wikipedia seems to be a heavily modified version thereof, and it appears to be proprietary. If anyone can find the repo, I'd appreciate a link.

DieBuche2• 15 years ago

What do you mean by heavily modified? Wikipedia is running version 1.17wmf, basically 1.17 with some fixes pulled from trunk. You'll find it here: http://svn.wikimedia.org/viewvc/mediawiki/branches/wmf/1.17w...

You'll find the installed extensions here: http://en.wikipedia.org/wiki/Special:Version

> It doesn't make any guesses, it doesn't look at related terms, and it often won't bring up the relevant article unless you specifically type that article's name.

I'm not sure it does the best job, but it does make guesses. For example, if you search for y cobbinator, it asks, Did you mean: y combinator. Though perhaps they should be more aggressive, like Google, and just go ahead and return the corrected results right away if the original query returned 0 results.

My girlfriend still types Facebook into Google to go to Facebook. I don't think it's an issue with Wikipedia.

chime• 15 years ago

A few years ago, I decided that I wanted to make a really good Wikipedia search engine. I downloaded the entire Wikipedia dataset, I downloaded DBPedia, I setup graph database, wrote code to query everything using SPARQL/RDF, and after much trial and error, went a completely different route: Google Ajax/JS Search API

http://chir.ag/wiki/cat+disease+brain

I did this because in the end, Google still gave very good results very fast. I made mine search-as-you-type so if I wasn't satisfied by the results, I could reedit my search text instantly.

I know because of Wikipedia's no-corporate-alliance reasons, they probably won't use Google search. If you're thinking of answering Greplin's call based on textual-analysis, my gut instinct says you will have a VERY hard time beating Google. However, if you go the DBPedia route, you might end up with something really neat. Powerset did something similar and got bought up by MS.

> I know because of Wikipedia's no-corporate-alliance reasons, they probably won't use Google search.

But perhaps some Googlers could volunteer their "20% time" applying their search knowledge (and relevant open-source code) to improve Wikipedia search.

asarazan• 15 years ago

It should be noted that the challenge is for design, not for actual search algorithm implementation or anything technical.

a3_nm• 15 years ago

I hope that the winning entry will be an actual implementation. It's not hard to have ideas to improve Wikipedia's search; the hard part is writing the code.

wturner• 15 years ago

I hope the winner gets built as a customizable addendum to the Mediawiki code and released as an extension. This way if Wikipedia doesn't use it other Mediawiki instances can.
