Should the query influence clustering of search results?

Author: Sudarshan Murthy


I notice some interesting differences between Google's search results for the queries else institute and the else institute: The results for else institute (try it) are clustered nicely under the link to the institute's home page. In contrast, the results for the else institute (try it) are not clustered and it contains fewer links. Snapshots of the query results are shown at the end of this post.

From the results, it looks like Google treats differently URLs "closer" to the query terms. Note that, in this case, the institute's web domain is "elseinstitute.org", but the institute's name is "The Else Institute". 

I don't understand why Google doesn't cluster both these search results the same way. In general, shouldn't the clustering be based purely on the results, and not on the query?
