Google toolbar and serps for searches from outside the US

[htdawg]

Does anyone know what the difference is for search results if you use
the search option from google's toolbar that says:

google web search
and then I have an option that says
search US

I am based in Greece and have google set to .com not .gr

so the results that I get from web search are very different from
the US search. which by the way have my pages show up better & higher for certain keyword phrases in the serps.

does that mean that people from the US see the better serps that I have?

I know that results are based on geolocation because I am in Greece
(IP)and my sites are .coms & hosted in the US, but are the US results what they really see?

Even within the US there are apparently different results. No longer is it possible to say "I am at #3 on that search." It's more like "I am at #3 on that search for people in the Northwest US who search on a week day using the IE browser who are not logged in to their Google account and who did not just make a similar search." And apparently there can be different results between using the toolbar and using google.com - and even searching at different times of the day or days of the week.
