I want to make a search engine which will use Google to search all the results but the difference will be that it will show results only from the websites which I select i.e. the search results will be from the selected websites whom I approve (putting approved URLs in a file and then using Google to search results from those websites).
How can I do this? I know Perl(beginner level) and HTML. How should I start working on it? Which things I must learn to achieve this goal? I need to know the procedure then I will do that task. Please let me know a good and efficient way to do this. Thanks :)
You probably want to use Google custom search.
