weird google results when searching for domain

[prawn]

I have a PR5 website which has been around for the past 4-5 years... lets call it www.foobar.com

This strange happening is into the end of its second month.

When I enter in www.foobar.com into the google search box, and click on
Find web pages that contain the term "foobar.com"
I get 1400 results returned.

When I enter in foobar.com into the google search box, and click on
Find web pages that contain the term "foobar.com"
I get ~938 results returned.

How is this possible! If anything there should be more results returned in foobar.com then www.foobar.com

Once in a while, I will get 2,650 results returned. But then when I got back immediatley and re-enter foobar.com i will get ~938 results returned. Everytime.

It looks like if its the first time for that day that I have entered foobar.com i get the 2,650... every try after that is ~938

Any ideas? Googledance... all servers seem to be the same...

Cheers

www.foobar.com and foobar.com are different so you will get different results.You may find also that google have no cache of one of them.Probably the foobar.com
