Is StartPage OK to hide search from Opera Proxy & ISP??????

If I go to https://StartPaqe.com
using a proxy web browser such as Opera
on Windows 7
and then search for "abc def"
and then go to web site https://web1.com

What does each of the peoples see?
~ I think https://web1.com obtain only the Opera Proxy IP Address
~ I think Start Page obtain only the search "abc def"
~ I think Opera Proxy Site Domain only see encryption messes?
~ I think ISP obtain only Opera Proxy IP Address

But is that correct?
What do each of these see?
~ Domain visited from a StartPage click
~ Startpage where the search was run and the link click
~ Opera Proxy Site Domain
~ Local ISP
