Your question is fabulous, the answer(s) could be taught in a "How to Understand Google and Websites" class.
IE 9 is your "Internet browser"; Google is your "search engine." The results of what you type into Google search will appear in a list format of websites that Google feels it has made a match for you.
When you click on a website, results show in the address bar (also location bar or URL bar). You will see the website name, words, symbols (etc.) which represent a "string". This is the "structure" of the website. It's a rather complex process to explain, to allow you to achieve a simple result!
Here is some information I found that might help you understand what you see in the address bar:
Almost every website on the Internet has a distinct design & organization structure. Experienced website designers usually create distinguishable layout templates for pages of different functions. They then organize the website by linking various pages with hyperlinks, each of which is represented by a URL string following some pre-defined syntactic patterns. This project is a reverse engineering to automatically discover the layout templates and URL patterns of a website, and understand how these templates and patterns are integrated to organize the website. To demonstrate the power of website structure understanding, this project also proposes some applications which leverage such site-level knowledge to help web search and data mining.
Take time to read the information in the link, and perhaps you will have a better understanding of what you have seen (i.e. +can+you+help+).
I hope this helps!
I look forward to other responses from other members or website builders as they explain why you see "%+can%+you%+help%+" in the address bar!
