........My questions are:

Is it possible to build a stealth search engine (web crawling not web scraping) to target just one website online, without them knowing, and how i.e. coding skills and anonymity required?

The website I am keeping tabs on has a new web page for each new product promotion , and each new page has a dynamic url (i.e. the URL contains a query with '?')

So I wonder if it is at all possible to build a search engine / web crawler to keep up to date with it.

In other words, I want to collect the subdomain URLs on a given website, and only those URLs that contain a certain word/phrase

Please advise on how to stay in stealth mode.

Please enlighten.

Thanks a million.
