How to perform a Specific URL Search?

Hi to all…
I have a question to the members…

In Google if we are looking for a specific domain or a keyword in the url …

How to perform that search using Google Advance Operators … or inurl search…

Please give me some advice…

Fail to understand the question… I assume that you want to know how many websites have that specific word in their domain?

Anyway, maybe this article can help

If you would like to search for a particular keyword then you can either type a query in a simple way or give it in a double quotes.
