HUsing the regular search engine, as a human, can get you not more than 1000 results, which is far more than a regular person needs.
But what If I do want to get 2000? is it possible? I read that it is possible using the App Engine or something like that (over here...), but, is it possible, somehow, to do it through Perl?
I don't know a way around this limit, other than to use a series of refined searches versus one general search.
For example instead of just "Tim Medora", I might search for myself by:
Search #1: "Tim Medora Phoenix"
Search #2: "Tim Medora Boston"
Search #3: "Tim Medora Canada"
However, if you are trying to use Google to search a particular site, you may be able to read that site's Google sitemaps.
For example, www.linkedin.com exposes all 80 million+ users/businesses via a series of nested sitemap XML files: http://www.linkedin.com/sitemap.xml.
Using this method, you can crawl a specific site quite easily with your own search algorithm if they have good Google sitemaps.
Of course, I am in no way suggesting that you exploit a sitemap for illegal/unfriendly purposes.
