While a search for "Wiki" on it's own does actually only search for Wiki, adding another word (eg. "Google" so you are searching for "Google Wiki") also searches for Wikipedia
http://www.google.com/search?&q=Google+wiki
I'm not sure on the exact search but what brought it to my attention was that one part that was highlighted was the start of "Wikipedia® is a registered trademark"
P.S. I'm not complaining 99.9% of the time I'm using this as a short cut to a Wikipedia article :D |
If you don't want that, add + in front of the keyword. E.g.: google +wiki. |
This is just another example of Google's stemming technology at work. |
I wouldn't call this stemming. Wiki and Wikipedia are not morphologically-related (Wikipedia is the name of a product). It's more like query expansion: including related forms, synonyms, related words along with a query. |
I guess I don't know my terminology in that case. Google says this:
<< Google now uses stemming technology. Thus, when appropriate, it will search not only for your search terms, but also for words that are similar to some or all of those terms. >>
I just figured that "wiki" and "wikipedia" are similar to each other. And "wikipedia" is blatently based on the word "wiki". |
this is usually incredibly useful when searching for wikipedia articles (quicker than using Wikiseek/Google site command).. |
OK sorry guess it does this with all queries with 2 or more words. "Goog Wiki" Also highlights "Google – Wikipedia" Just thought Google where assuming things |
Mrrix32: GOOG is Google's NASDAQ stock symbol, so it's not surprising that it's treated as a synonym for Google. What does surprise me is that this is only done for queries of two words or more. |
The query expansion depends on the context and a single word is not a context. Acronyms are expanded, though: http://www.google.com/search?q=ms |
Roger Yeah but Goog on it's own doesn't highlight Google, which was the point I was making |
