mydomain.com was dropped out from Google in August

Hi.

[google.com...] ... returns 0 results
[google.com...] ... returns 12,000 results

[google.com...] ... returns 5,650,000 results
[google.com...] ... returns 5,660,000 results
(this last test works with *any* domain)

Which is the difference? 'mydomain.com' was completely dropped out from Google

Why doesn't Google return any result of 'allinurl:mydomain.com' when you don't activate the duplicated-content filter and a lot of results when you activate it? I'm looking for any tip to explain my Google vanishment.

My website was dropped out from Google in late August, just after changing my URL system.

Any suggestion? Thank you very much.

I haven't researched this very much -- maybe someone else has?
